Question

a spinner has 20 equally sized sections, 2 of which are green and 18 of which are blue. The spinner is spun and, at the same time , a fair coin is tossed. what is the probability, that the spinner lands on green and the coin toss is tails?​

Answer 1

The probability of getting the spinner to land on green and coin to show Tails is 1/20

Explanation:

p(E) = p(spinner landing on green) = 2/20

p(F) = p(Coin lands on Tails) = 1/2

p(E and F) = p(E) . p(E/F)

p(E and F) = 2/20 . 1/2

p(E and F) = 1/20

The probability of getting the spinner to land on green and coin to show Tails is 1/20
