Answer:
P(n) = 0.5
Step-by-step explanation:
For two events which are independent, we use the multiplication rule which states P (A and B) = P(A) * P(B). Substitute P(m) = 0.4 and P(m and n) = 0.2 into this formula.
P (m and n) = P(m) * P(n)
0.2 = 0.4*P(n)
Divide by 0.4 on both sides.
0.2 / 0.4 = P(n)
0.5 = P(n)
Answer:
It is 1/11
Step-by-step explanation:
Apply the rule a/c +- b/c = a+-b/c
=8-7/11
=1/11
Answer:
74 degrees
Step-by-step explanation:
The two angles in question form a straight line (180 degrees)
180 = CHF + FHD
180 = 106 + FHD
180 - 106 = FHD
FHD = 74 degrees
