Answer:
0.30
Step-by-step explanation:
Probability of stopping at first signal = 0.36 ;
P(stop 1) = P(x) = 0.36
Probability of stopping at second signal = 0.54;
P(stop 2) = P(y) = 0.54
Probability of stopping at atleast one of the two signals:
P(x U y) = 0.6
Stopping at both signals :
P(xny) = p(x) + p(y) - p(xUy)
P(xny) = 0.36 + 0.54 - 0.6
P(xny) = 0.3
Stopping at x but not y
P(x n y') = P(x) - P(xny) = 0.36 - 0.3 = 0.06
Stopping at y but not x
P(y n x') = P(y) - P(xny) = 0.54 - 0.3 = 0.24
Probability of stopping at exactly 1 signal :
P(x n y') or P(y n x') = 0.06 + 0.24 = 0.30
Answer:
a = a
b = b
c = c
Step-by-step explanation:
Formula: 
C is always the largest number
<em><u>a times a + b times b = c times c</u></em>
Answer:
36.07 million percent
Step-by-step explanation:
Answer :
- Total number of people in the room = 18
- Number of people with red hair = 2
- Number of people not with red hair = 18 - 2 = 16
- Probability of picking a person who doesn't have red hair =

Probability = 16/18
Reduce the fraction with 2
Probability = 8/9
