Question

There are 5 marbles in a bag: 4 are blue, and 1 is red. What is the probability that a blue marble gets picked?

Answer 1

Answer:

4/5

Step-by-step explanation:

Probability = favourable outcomes/total outcomes

P (blue marble) = 4/5

Answer 2

The probability is 4/5.

Given - Number of marbles

Find - Probability

Solution - Probability = number of favourable outcomes/Total number of outcomes

Number of favourable outcomes = Number of blue marbles

Number of favourable outcomes = 4

Total number of outcomes = Number of us marbles + number of red marbles

Total number of outcomes = 4 + 1

Total number of outcomes = 5

Probability = 4/5

Hence, probability that a blue marble gets picked is 4/5.
