Question

The experimental probability of a coin landing on heads is 7/12. If the coin landed on tails 30 times, find the number of tosses

Answer 1

Answer: 72 tosses

Explanation: If the probability of landing heads is 7/12, the probability of landing tails is 5/12. So then you do cross multiplication, where you multiply the 12 and the 30, equalling 360. Then divide that by 5, equalling 72.
