If there are 45 guests at the party, predict how many would choose a gift card?

Mathematics
1 answer:
sergij07 [2.7K]3 years ago
4 0

Answer:

Since there is a 50-50 chance of a person at the party choosing a gift card, and since there can only be 1 of 2 outcomes, we can assume that there will either be more people choosing a gift card than not, or there will be more people not choosing a gift card than are. So, that means that there would be 23 people (more or less) choosing a gift card and 22 people (more or less) not choosing a gift card or vice-versa.
