Step-by-step explanation:

Given:-

A bag contains 2 blue marbles, 7 green marbles, 4 yellow marbles, and 3 purple marbles.

To find:-

What is the probability of pulling a Yellow marble out of the bag?

Solution:-

Total number of blue marbles = 2

Total number of green marbles = 7

Total number of yellow marbles = 4

Total number of purple marbles = 3

Total number of marbles in the given bag

=2+7+4+3

=>16

Total number of marbles = 16

Total number of all possible outcomes = 16

We know that

Probability of an event E = P(E)=

No. of favourable outcomes /

Total no. of all possible outcomes

Probability of getting a yellow marble out of the bag is P(Y)

= No.of favourable outcomes to yellow marble /

Total no. of all possible outcomes

=>P(Y)= 4/16

=>1/4

Answer:-

Probability of getting a yellow marble out of the bag is P(Y) = 1/4

Used formula:-

Probability of an event E = P(E)=

No. of favourable outcomes / Total no. of all possible outcomes
