An opaque bag contains 5 green marbles 3 blue marbles and 2 red marbles. what is the of randomly picking out a marble and the marble being red?

Answers

Answer 1

Answer:

The probability of randomly picking out a red marble is 1/5

Calculating the probability of randomly picking out a marble and the marble being red?

To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.

Total marbles = 5 green + 3 blue + 2 red = 10 marbles

Red marbles = 2

So, we have

Probability = (Number of favorable outcomes) / (Total possible outcomes)

This gives

Probability = (Number of red marbles) / (Total marbles)

By subsituition

Probability = 2/10 = 1/5

Hence, the probability of randomly picking out a marble and it being red is 1/5

12×2=24

So 24 cubic inches can be fit into a empty box with a volume of 2 cubic feet.
Hope this helps!

1 feet= 12 inches
2 feet= 12 times 2 = 24 inches

24 inch cube can fit into an empty box with the volume of 2 cubic feet

Thirty people are eligible to win cash prizes. The number of each cash award prize is shown in the table. Prizes will be given out randomly one at a time. What is the probability of the first person winning the $50 prize?

Answers

Answer:

0.1667

Step-by-step explanation:

Given that the Total number of people who are eligible to win cash prizes is 30.From the given table we notice that 5 people win $50 cash prize.

The probability of the first person winning the $50 prize is therefore :

$p=(Number \ who \ win \ \%50)/(Total \ no \ of \ people)\n\n=5/30\n\n=(1)/(6)=0.1667$

Hence the probability of the first person winning the $50 prize is 0.1667
