Question

A bag contains 75 red balls, 25 green balls and 90 blue balls. A ball is taken out from the bag at random
a. What is the probability that the ball is not a blue balls?
b. What is the probability of getting red ball ?​

Answer 1

Answer:

the answer is as follows

Step-by-step explanation:

a) LET E be the event

E = getting a ball either green or red

total balls = 75+25+90=190

 p(E) = 100/190 = 10/19

b) Let E1 be an event

E = getting a red ball

P(E1) = 75/190 = 15/38
