First, what you would do is multiply 140 and 20%. Which would give you: 28
Then you would multiply 28 by 4 and get 112
Hope this helps!!(:
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
Answer:
The length of the window is 35 inches.
Step-by-step explanation:
Perimeter of an object can be found using the general formula: P = 2W + 2L, where P = perimeter, W = width and L= length. Since both the width and perimeter of the window are given, we can plug these values into the formula to solve for the missing variable 'L': 112 = 2(21) + 2L, or 112 = 42 + 2L. We can then use inverse (opposite) operations to isolate the variable and solve. Whatever we do to one side of the equation, we do to the other. We will start by subtracting 42 from each side: 112 - 42 = 42 - 42 + 2L or 70 = 2L. Next, we divide both sides by 2 to solve for L: 70/2 = 2L/2 or L = 35. So, the final length of the window is 35 inches.
