Answer:

let R represent red hair

let G represent green eyes

<em>from</em><em> </em><em>Baye's</em><em> </em><em>theorem</em><em>:</em>

<em>P( \frac{R}{G} ) =  \frac{P(RnG)}{P(G)}</em>

P(RnG) = 5

P(G) = { \sum}(green \: hair) \\  = (3 + 5 + 5) \\  = 13

Therefore:

P( \frac{R}{G} ) =  \frac{5}{13}  \\  = 0.385

The conditional relative frequency = 0.385

If a dart board was thrown randomly at the dartboard shown below, what is the probability that it will land in the bull’s-eye? T
vampirchik [111]

Answer:

Correct option: C -> 2%

Step-by-step explanation:

To find this probability we just need to divide the area of the bull's-eye circle by the total area of the outer circle.

The area of a circle is given by the equation:

area = \pi * radius^2

The outer radius is 14 cm, so:

outer\ area = \pi * 14^2 = 196\pi\ cm^2

The inner radius is 2 cm, so:

inner\ area = \pi * 2^2 = 4\pi\ cm^2

So the probability is:

inner\ area / outer\ area = 4\pi / 196\pi = 0.02 = 2\%

Correct option: C
