Question

there are four red 5 black and 2 white balls of the same size and shape in a box a ball is draw randomly what is the probability of a ball being black or white​

Answer 1

Step-by-step explanation:

P(E)=no of possible events/all the possible events

total no of balls= total no of possibilities=5+2+4=11

P(getting black ball)=5/11=0.45

P(getting red ball)=4/11=0.36

P(getting a white ball)=2/11=0.18

hope it helps ☺️
