The probability that a male professional golfer makes a hole-in-one is 1/2780. Suppose 36 professional male golfers play the six

yuradex [85]

Answer:

The right solution is " $9.7\times 10^{-10}$ ".

Step-by-step explanation:

According to the question,

The probability that male professional golfer makes hole in one will be:

$P=\frac{1}{2780}$

Number of players,

n = 36

and,

$q=1-P=\frac{2779}{2780}$

By using the Binomial theorem, we get

⇒ $P(x=r) = \binom{n}{r} p^r q^{n-r}$

Bu substituting the values, we get

$=\binom{36}{4} (\frac{1}{2780} )^4 (\frac{2779}{2780} )^{32}$

$=9.74929\times 10^{-10}$

or,

$=9.7\times 10^{-10}$

If a archery set's original price is $94.00 and the sale price is $61.10 what percent is the discount

valkas [14]

Answer:

The discount is 35%.

Step-by-step explanation:

94 - 61.10 = the amount that she got discounted for.

Which equals $32.90. She got discounted $32.90 dollars. To find out the percent of cash she got discounted for you would do:

$32.90 divided by $94.00

Which equals .35

Move the decimal over 2 places to the right, and you then have your answer, which is 35%.

She got discounted 35%.
