Question

A ball is drawn at random from a box containing 4 blue balls, 5 red balls and 6 white balls find probability red and white

Answer 1

Step-by-step explanation:

Total number of balls =4+5+6=15 N(S)=15

P(getting Red balls)=N(E)/N(S)

=5/15

=1/3

P(getting White balls)=N(E)/N(S)

=6/15

=2/5

Answer 2

Step-by-step explanation:

total balls=15

probability of getting red balls=5/15=1/3

probability of getting white balls=6/15=2/5

probability of getting red and white balls=1/3+2/5=11/15.

pls mark it as a brainliest answer.
