Question

There were 8 socks of white, green and blue shuffled in a draw. The probability of selecting a white sock is 1/4. What is the probability of selecting a green sock if the probability of selecting the yellow sock is 5/8?

Answer 1

ANSWER IS 1/8

Step-by-step explanation:

P(White sock) = 1/4

P(yellow sock) = 5/8

Now,,

P(white sock) + P(yellow sock) + P(green sock) = 1

1/4 + 5/8 + P(green sock)=1

7/8 + P(green sock) = 1

P(green sock) = 1 - 7/8

P(green sock) = 1/8

Answer 2

Answer:

p(getting a green rock) = 1/8

Step-by-step explanation:

total rocks = 8

p(getting a white rock) = 1/4

p(getting a yellow rock) = 5/8

let probability of green rock is x

sum of all probability = 1

=> 1/4 + 5/8 + x = 1

=> 2/8 + 5/8 + x = 1

=> x = 1 - 7/8

=> x = 1/8

therefore,

p(getting green rock) = 1/8

hence proved
