Question

At a carnival game, a large horizontal board has holes of the same size cut in it. For the game, you toss a ball onto the board and it lands or rolls into one of the holes. The board is surrounded on all sides, so the ball is certain to fall in a hole. Three of the holes will earn a small prize and one of the holes will earn a large prize. If Grady buys a ticket for one ball that he'll toss on the board, what is the probability that he'll win a prize?

Wouldn't the answer be 5%?

(Please explain in steps even if it's right or wrong)

Answer 1

20 sorry.

Answer 3

XD no the anwser will not be 5%

Answer 4

Answer 8

since there is 4 holes with prizes out of 20 holes

Answer 9

it would be 4/20 which equals...

Answer 10

So what do I do.. to solve is there a formula? Like P(event)=number of favorable outcomes/number of total outcomes..? IM SO CONFUSED D:

Answer 11

no. no formulas involved it is a logic and probability question

Answer 12

So what do I do? How did you get that fraction?

Answer 13

the question askes for the probability of grady getting a prize

since there is 3 holes for small prizes and 1 hole for a large prize
there is a total of 4 prize holes out of 20
there fore the fraction you get is 4/20

Answer 14

and 4/20 equals....

Answer 15

.2 x 100 = 20%

Answer 16

So you total them all and then make a fraction?... I get it now :D

Answer 17

XD yeah basically
