Answer:
≈0.76
Step-by-step explanation:
P(A) = 0.33
P(A and B) = 0.25
P(B) = ?
-------------
<u>Probability of two events happening is the product of individual probabilities</u>
<u>Then to find the probability of one of the events: </u>
- P(B) = P(A and B) / P(A)
- P(B) = 0.25 / 0.33 ≈ 0.76
Let the first number be x
The second number is x + 2
The third number is x + 4
x + x + 2 + x + 4 = 270
3x = 270 - 6
x = 88
x is not prime so there is no first number!
15, because of the Pythagorean triple 8, 15, 17.
