=3/4 answer

hope it helped....please mark it as a brainlist answer

Answer 2

The probability of withdrawing a red ball is $\frac{3}{7}$

Given,

Number of red balls = 3

Number of blue balls = 4

To Find,

Probability of drawing a red ball from the bag

Solution,

The probability of a certain occurrence is given by the ratio of the number of outcomes favoring that situation to the number of the total outcomes.

Probability = $\frac{Number of favorable outcomes}{Number of total outcomes}$

The favorable outcome in this situation is drawing out a Red ball

Number of Red balls = 3

Total Number of outcomes = 3 + 4 = 7

Probability = $\frac{3}{7}$

Thus, the probability of withdrawing a red ball is $\frac{3}{7}$
