Question

Natasha Romanov is really good at playing darts. She can hit a bullseye about 95% of the time. How many throws will she
need in order for her to hit 76 bullseyes?

Answer 1

Given that,

Natasha can hit a bullseye about 95% of the time

we've to find the number of throws will she

need in order for her to hit 76 bullseyes

for that, we'll divide 76 by 95%

$\huge \rightarrow \: 76 \div \frac{95}{100} = \frac{76}{\frac{95}{100} }$

$\huge \rightarrow76 \times \frac{100}{95}$

$\huge \rightarrow80$

Hence, she need 80 bullseye in order for her to hit 76 bullseyes

Answer 2

Answer:

Step-by-step explanation:

P(hit a bulleye) = 95% = 0.95

P(hit 2x bulleyes) = 0.95*0.95

P(hit 76x bulleyes) = 0.95^76

= 0.02

So she will hit 76 bulleyes on average every 1/0.02 = 50 times.

Total number of throws = 50 x  76

= 3800
