Question

2. Find the probability of picking up 2 red balls from a bag containing 4 red balls and 6 white balls.​

Answer 1

Answer:

1 ÷ 5

Step-by-step explanation:

Sample space = S contains 4 red ball and 6 white ball

S = { R1 , R2 , R3 , R4 , W1 , W2 , W3 , W4 , W5 , W6 }

n( S ) = 10

EVENT A = 2 RED BALL

A ={ R1R2 , R3R4 }

n( A ) = 2

P ( A ) = n(A) ÷ n(S)

= 2 ÷ 10

= 1 ÷ 5
