Question

The odds that it will snow tomorrow are 9 to 6. What is the probability that it will not snow tomorrow?a) 0.1818

Answer 1

Answer:

a) 0.1818

Step-by-step explanation:

Given that:

The odd that it'll snow tomorrow is 9 to 6

The probability that it will snow tomorrow  $=\dfrac{9}{9+6}$

$=\dfrac{9}{15}$

= 0.6

The probability that it'll not snow tomorrow $= 1 - \dfrac{9}{15}$

$= \dfrac{15-9}{15}$

$=\dfrac{6}{15}$

= 0.4

Let assume that the odd that it'll snow tomorrow is 9 to 2

The probability that it will snow tomorrow  $=\dfrac{9}{9+2}$

$=\dfrac{9}{11}$

= 0.8181

The probability that it'll not snow tomorrow  $= 1 - \dfrac{9}{11}$

$= \dfrac{11-9}{11}$

$=\dfrac{2}{11}$

= 0.1818
