Question

question avanis school is selling 100 raffle - tickets to raise money for a new gymnasium. the grand - prize is a ten - speed mountain bike. which word or phrase describes the probability that she will win the raffle if she buys all the tickets? answer impossible unlikely an equal chance or 50 - 50 certain

Explanation:

Step1: Analyze the probability concept

If Avani buys all 100 raffle - tickets, then the number of favorable outcomes (her winning) is equal to the total number of possible outcomes (since there are no other tickets for others to win).

Step2: Determine the probability description

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, if she buys all tickets, \(\text{Number of favorable outcomes}=100\) and \(\text{Total number of outcomes}=100\), so \(P = 1\). A probability of \(1\) means the event is certain to happen.

Answer:

certain
