Question

A ball is drawn randomly from a jar that contains 3 red balls, 8 white balls, and 2 yellow ball. Find the probability of the given event.
(a) A red ball is drawn;
The probability is :   
(b) A white ball is drawn;
The probability is :   
(c) A red or white ball is drawn;
The probability is :   

Answer 1

Prob. = number of favorable cases /total cass

Total balls =3+8+2=13

A)

P(red balls) =3/13=0.231

B)

P(white balls) =8/13=0.615

C)

P(red or white) =P(white) +P(Red) =0.615+0.231

P(Red or white) =0.846
