A bag contains 2 blue marbles, 7 green marbles, 4 yellow marbles, and 3 purple marbles. 11) What is the probability of pulling a Yellow marble out of the bag?
Answers
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
