Angle L = Angle J (Opposite angles are equal)

Angle L = 98

Angle K + Angle L = 180 (Adjacent angles are supplementary)

Angle K + 98 = 180

Angle K = 180 - 98

Angle K = 82

Angle M = Angle K (Opposite angles are equal)

Angle M = 82

Monica took a survey of her classmates' hair and eye color. The results are in the table below.

jolli1 [7]

Answer:

let R represent red hair

let G represent green eyes

from Baye's theorem:

$P( \frac{R}{G} ) = \frac{P(RnG)}{P(G)}$

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
