People with restless leg syndrome have a strong urge to move their legs to stop uncomfortable sensations. People with fibromyalg

USPshnik [31]

Answer:

0.1833

Step-by-step explanation:

Given:

% of people with fibromyalgia = 2%

Probability of having a restless leg syndrome for people with fibromyalgia = 0.33

Probability of having a restless leg syndrome for people without fibromyalgia = 0.03

Take F as event of having fibromyalgia

Take R as event of having restless leg

Required:

Find the probability that a person with restless leg syndrome has fibromyalgia.

To find the probability that a person with restless leg syndrome has fibromyalgia, we have: P(F/R)

$P(F/R) = \frac{P(F n R)}{P(R)}$

$P(F/R) =\frac{P(R/F) * P(F)}{P(R/F) * P(F) + P(R/F^c) * P(F^c)}$

Where,

P(R/F) = 0.33

P(F) = 2% = 0.02

P(R/F') = 0.03

P(F') = 1 - 0.02 = 0.98

Therefore,

$P(F/R) = \frac{0.33 * 0.02}{0.33*0.02 + 0.03*0.98}$

= 0.1833

Probability a person with restless leg syndrome has fibromyalgia = 0.1833

A bag contains 8 white, 4 red, 7 green, and 5 blue marbles. Eight marbels are withdrawn randomly. How many withdrawn marbles wer

Wewaii [24]

We are starting with 8+4+7+5=24 marbles. We're taking out 8, so we'll be left with 24-8=16 marbles. Think about those 16. If the probability of drawing a white one is 1 in 4, that means that 1/4 of the marbles are white. 1/4 of 16 is 16/4 = 4 marbles are white. Since we started with 8 white, and there are 4 left, we must have taken out 8-4 = 4 white marbles.
