Question

A bag contains 7 blue balls,6 red balls and 2 yellow balls. Find the probability of each. a. Getting a red ball b. Getting a yellow ball

Answer 1

A bag contain balls 7 blue,6 red,and 2 yellow

then sample space.

S= { 7,6,2 }

n(S)=15

Let event A be the red ball.

A= { 6 }

n(A)=6

p(A)= n(A)/n(S)

=6/15

=2/5

Let event B be the blue balls

B= { 7 }

n(B)= 7

p(B)= 7/15

Let event C be the yellow balls

C={2}

n(S)= 2

p(c)= 2/15

i hope understand you...
