You dint know what going to tell me Abe's and you can tell that she's hitting in the shower now I know I will ince and but 7. C is the answer
First you need the size of an angle QPR = B = 180° - 123°
Lenght of QP = 10cm
QR = x
QP = r
x² = r² + r² - 2r² × cosB
Answer:
Yeah I'm here harmony plz tell
Step-by-step explanation:
Answer:
The events are not mutually exclusive because the P(A and B)=0.1 not 0
Step-by-step explanation:
Mutual exclusive events are those that can't happen at the same time.For example Tossing a coin, Head and Tail are mutually exclusive events because you can't get a Head and a tail at the same time.Another example is turning left and turning right are mutually exclusive because you can't do both at the same time.
If events are mutually exclusive, they can happen at the same time.
Mathematically,the probability of mutual exclusive events follows;
P(A and B)=0 ------------The probability of A and B together equals 0
P(A or B) = P(A)+P(B)-----The probability of A or B equals the probability of A plus the probability of B.
In this question you are given;
P(A)=0.3
P(B)=0.6
P(A or B) =P(A) + P(B)= 0.3+0.6 =0.9
0.9≠0.8 thus the events are not mutually exclusive.
For number 14 it's 0.35 that the answer but do the calculator if u don't know how to do fraction do division because fraction are division remember that
