Answer:
0.5
Step-by-step explanation:
-0.35 x 1.43=0.5
3/7= .43
<em>d = 2r => r = d/2 = 15cm/2 = 7,5 cm</em>
<em />
<em>V = π·r² = 3,14·(7,5)² = 3,14·56,25 = 176,625 ≈ 176,6 cm³</em>
Answer:
(a) 0.42
(b) 0.28
(c) 0.88
Step-by-step explanation:
Let probability that the bank stock will appreciate over a year, P(A) = 0.70
Probability that the electric utility will increase over the same period, P(B) = 0.60
Also, it is given that the two events are independent.
(a) Probability that both stocks appreciate during the period = Bank stock will appreciate * Electric utility will appreciate = P(A) * P(B)
= 0.70 * 0.60 = 0.42 .
(b) Probability that the bank stock appreciates but the utility does not is given by;
P(A) * (1 - P(B)) = 0.70 * (1 - 0.60) = 0.70 * 0.40 = 0.28 .
(c) Probability that at least one of the stocks appreciates = P(A B)
P(A B) = P(A) + P(B) - P(A B)
= 0.70 + 0.60 - (0.70 * 0.60) { because both events are
independent }
= 1.3 - 0.42 = 0.88 .
