Answer:
<u>1/8910720</u>
Step-by-step explanation:
Number of ways they can be chosen :
⇒ 17 × 16 × 15 × 14 × 13 × 12
⇒ 272 × 15 × 14 × 13 × 12
⇒ 4080 × 14 × 13 × 12
⇒ 57120 × 13 × 12
⇒ 742560 × 12
⇒ <u>8910720</u>
Hence, the probability will be :
⇒ P = 1 / number of ways
⇒ P = <u>1/8910720</u>
5/ sqrt (10)
no radicals in the denominator so we multiply by sqrt(10)/sqrt(10)
5/ sqrt (10)* sqrt(10)/sqrt(10)
5 * sqrt(10)

Answer:
11
Step-by-step explanation:
Let a= times he hit 4 par
Let b = times he hit 5 par

4a+5b=79
b=79-72=7
So a = 11
