At a golf course there are 18 holes. of the 18 holes 3 are par threes 8 are par fours and 7 are par fives what fraction of the holes are par threes par fives and par fours

The fraction of holes that are par three is

The fraction of holes that are par four is

The fraction of holes that are par five is

Solution:

Given that At a golf course there are 18 holes

Therefore,

Total number of holes = 18

Of the 18 holes 3 are par threes 8 are par fours and 7 are par fives

So there are par 3, par 4 and par 5

Number of par 3 holes = 3

Number of par 4 holes = 8

Number of par 5 holes = 7

To find: fraction of the holes that are par threes Par fives and par fours

Thus the required fractions are found

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
