Answer:
Hence experimental probability that all 3 coins show the same result when he tossed it for 50 times and 8 of those are of success is 0.04
Step-by-step explanation:
Given:
3 coins are tossed at same time
No of trails are 50 and
success for trails are 8.
To Find:
Experimental probability for 3 coins that getting all heads or all tails.
Solution:
Now
When only 3 coins are tossed probability that getting all heads is as follows:
Calculating the sample space of the event
Event is 3 coins are tossed at a time
So Sample space S={HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
n(S)=8
No of trails getting all heads is 1
So P(getting all heads )=1/8
Same of tail i.e. 1/8
Adding both will be required probability for getting all heads or tails
here or ' operator so Addition
1/8+1/8=2/8
=1/4
1/4 is probability that the all heads or all tails when coins is tossed one time
but here it is about 50 times and probability if successs trails are 8
Hence
Now
Probability of success P=8/50=0.16
Probability of getting all heads and all tails in 50 trails of which 8 are only success
Hence required Probability =Probability of success *Probability of getting all heads or tails
=0.16*(1/4)
=0.16*0.25
=0.04
Hence experimental probability that all 3 coins show the same result when he tossed it for 50 times and 8 of those are of success is 0.04
2, 2, 25, 25, 26, 26, 27, 28, 28, 30
Minimum: 2
Maximum: 30
Median: 26
Lower quartile: 25
Upper quartile: 28
The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.
Just so you know, I didn't write this. Next time, do a google search for your answer. But in the mean time, here you go.
Answer: Number 3- The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.
Step-by-step explanation:
The following data show the prices of different types of outfits at a store:
$2, $2, $28, $26, $25, $27, $25, $27, $26, $28, $30
Which statement is correct about the box plot for the above data? (1 point)
1. The box plot will have its right tail longer than the left tail because a few exceptionally low prices make the distribution skewed to the right.
2. The box plot will have its right tail longer than the left tail because a few exceptionally low prices make the distribution skewed to the left.
3. The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.
4. The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the right.
The two $2 at the beginning of the data are outliers. They are exceptionally lower than all the other numbers, meaning they will be alone at the beginning of the data. That is the left! Now, it is number 3 and not 4 because it makes the data skewed to the left because of the low prices, not right. The two $2 hang off to the left. Which means the answer is number 3!
3. The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.
