Answer 4

Correct way P{ not pink}

Answer 5

Answer 6

The probability of not selecting a pink eraser can be found by adding the probabilities of selecting erasers that are not pink. There are 5 green erasers, 2 striped erasers, and 3 white erasers, so the probability of not selecting a pink eraser is:

P(not pink) = P(green) + P(striped) + P(white)

P(not pink) = 5/14 + 2/14 + 3/14

P(not pink) = 10/14

P(not pink) = 5/7

Therefore, the probability of selecting a pink eraser is:

P(pink) = 1 - P(not pink)

P(pink) = 1 - 5/7

P(pink) = 2/7
