ddd [48]

Answer:

P(t)= 100t + 150

In Vancouver, British Columbia, the probability of rain during a winter day is 0.42, for a spring day is 0.23, for a summer day
nadezda [96]

Answer:

31.82% probability that this day would be a winter day

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening

In this question:

Event A: Rain

Event B: Winter day

Probability of rain:

0.42 of 0.25(winter), 0.23 of 0.25(spring), 0.16 of 0.25(summer) or 0.51 of 0.25(fall).

So

P(A) = 0.42*0.25 + 0.23*0.25 + 0.16*0.25 + 0.51*0.25 = 0.33

Intersection:

Rain on a winter day, which is 0.42 of 0.25. So

P(A \cap B) = 0.42*0.25 = 0.105

If you were told that on a particular day it was raining in Vancouver, what would be the probability that this day would be a winter day?

P(B|A) = \frac{0.105}{0.33} = 0.3182

31.82% probability that this day would be a winter day

The supreme choice pizza at Pizza Paradise contains 22 different meats and 33 different vegetables. The customer can select any
mash [69]

Answer:

1680 possible pizzas

Step-by-step explanation:

Pizza contains 2 different meat and 3 different vegetables.

If there are 5 meats and 8 vegetables, the customer can select any one of 3 types of crust.

Total number of ways to select meat = 5C2

nCr = n! /(n-r)! r!

5C2 = 5! / (5-2)!2!

= 5! / 3!2!

= 10

Total number of ways to select vegetables = 8C3

= 8!/(8-3)!3!

= 8! / 5!3!

= 56

Total number of pizza choice that can be made = 3 * 5C2 * 8C3

= 3*10*56

= 1680 possible pizza
