Answer:
P(A and B) = 0.21
Step-by-step explanation:
Two events are said to be independent when the occurrence of event 1 does not affect the occurrence of event 2
Given two probabilities A and B whose probabilities are given as follows
P(A) = 0.3, P(B) = 0.7
P(A and B) is calculated as follows;
P(A and B) is calculated by multiplying both probabilities together
P(A and B) = P(A) * P(B)
P(A and B) = 0.3 * 0.7
P(A and B) = 0.21
Hence, P(A and B) = 0.21
Answer:
0.21
Step-by-step explanation:
If A and B are independent, then:
P(A and B) = P(A) × P(B)
Given P(A) = 0.3 and P(B) = 0.7:
P(A and B) = 0.3 × 0.7
P(A and B) = 0.21

we know that
Applying the law of cosines

substitute the values and solve for cos(A)

![cos(A)=[22^{2}+18^{2}-31^{2}]/(2(22)(18))\\ \\cos(A)=-0.193182\\ \\A=arccos(-0.193182)=101\°](https://tex.z-dn.net/?f=cos%28A%29%3D%5B22%5E%7B2%7D%2B18%5E%7B2%7D-31%5E%7B2%7D%5D%2F%282%2822%29%2818%29%29%5C%5C%20%5C%5Ccos%28A%29%3D-0.193182%5C%5C%20%5C%5CA%3Darccos%28-0.193182%29%3D101%5C%C2%B0)
