Answer:
0.50
Step-by-step explanation:
Let A represent the probability that it will be cloudy
Let B represent the probability that it will be rainy
P(A) = 0.40
P(B) = 0.30
P(A and B) = 0.20
For non mutually exclusive events the probability of event A or B is
P(A or B) = P(A) + P(B) - P(A and B)
= 0.40 + 0.30 - 0.20
= 0.50
There is a 50% probability that the picnic will be postponed. Therefore the probability that the picnic will not be postponed is equals 1 - P(A and B)
= 1 - 0.50
= 0.50 or 50%
Answer:
11.2 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opposite side/ adjacent side
tan 66 = BC/ 5
Multiply each side by 5
5 tan 66 = BC
11.23018387 = BC
Rounding to the nearest tenth
11.2 = BC
