Daniel buys 17 raffle tickets.
A total of 280 tickets were sold.
Find the probability that Daniel does not win the prize.​

Answer 1

Answer:

263/280 or 0.9

Step-by-step explanation:

Daniel has 17 raffle tickets which is 17 chances of winning. The question is probability that Daniel does not win the prize.

so, P ( Daniel does not win the prize)

= 280-17/280

=263/280

Answer 2

The probability that Daniel will not win the prize is 0.93.

Given:

Number of tickets bought by Daniel = 17

total number of tickets sold = 280

To Find:

the probability that Daniel does not win the raffle prize.​

Solution:

The formula for calculating probability is given as-

Probability of an event = number of favorable outcomes/Total number of outcomes

Daniel will not win the prize if his ticket is not selected

Number of tickets that will not get Daniel the price = 280 - 17

= 263

Thus, probability = 263/280

= 0.93

Hence, the probability that Daniel will not win the prize is 0.93.
