Step-by-step explanation:
The simplifying of the expression will be -12a+102
Answer: 0.001
Step-by-step explanation:This is a combination problem, so we need to calculate the combination of 7 choose 5, and then multiply by the probability of each event:
Combination of 7 choose 5:
C(7,5) = 7! / (5! * 2!) = 7*6/2 = 21
This value means that we have 21 different possibilities of the 5 days we want being allocated in the 7 days
Now, the probability of each event is:
5 days playing the song: (0.15)^5
2 days not playing the song: (0.85)^2
So, the final probability is
P = C(7,5) * (0.15)^5 * (0.85)^2 = 0.001
<u>Answer:</u>
Two events, A and B, are independent. If P(A) = 0.3 and P(B) = 0.2.The value of P(A and B) is 0.06
<u>Solution:</u>
Given that P(A) and P(B) are two independent events which means the occurrence of one event does not affect the occurrence of another event.
Here we have to find out P(A and B)
When P(A) and P(B) are two independent events, then P(A and B) can be found out by,
P(A and B) = P(A) P(B)
Given that P(A) = 0.3 and P(B) =0.2
P(A and B) = 0.3 0.2
P(A and B)= 0.06
Thus the value of P(A and B) is 0.06
