Question

Suppose you Flip a coin and spin a spinner with four equal sections labeled 1-4 if you repeat this process 1,000 times what is the best prediction for the number of times the coin will land on heads and the spinner will land on a 2

Answer 1

125 times.

Explanation:

Prob(Heads) = 1/2.

Prob(Spinner lands on 2) = 1/4 ( as there are 4 sections on the spinner).

So the best prediction for the number of times this occurs in a 1000 trials

= 1/2 * 1/4 * 1000

= 1/8 * 100

= 125 times.
