P(A)=0.22 and P(B)=0.46 Find P(A OR B)

Mathematics

morpeh [17]4 years ago
4 0

In general, the probability of a disjunction is

P(A \lor B) = P(A)+P(B)-P(A\cap B)

In this case, A and B are mutually exclusive, so P(A\cap B)=0

This simplifies the formula to

P(A \lor B) = P(A)+P(B) = 0.22+0.46 = 0.68

ziro4ka [17]
If the snow falls at a rate of 1.3 inches per hour, dividing 6.825 into 1.3 should give you your answer.
6.825/1.3 = 5.25
Therefore, the snow was falling for 5.25 hours, or 5 hours and 15 minutes.

I need help please
guajiro [1.7K]

Answer:

distance = 10.6

Step-by-step explanation:

A's coords are (5, 6)

D's coords are (-2, -2)

So the total horizontal distance between A and D is:

5 + 2 = 7

...and the total vertical distance is:

6 + 2 = 8

Now use Pythagorean Theorem:

7^2 + 8^2 = distance^2

distance^2 = 49 + 64 = 113

distance = squareroot of 113

distance = 10.6
