Answer:
B) 0.55
The probability of the complement of Event A ( P( A⁻ )) = 0.55
Step-by-step explanation:
<u>Explanation</u>:-
<em> Given Event A and Event B are mutually exclusive.</em>
<em> Given data P(A) = 0.45
</em>
<em> P(B) = 0.35</em>
<em> P(C) = 0.25</em>
<em>The probability of the complement of Event A</em>
<em> P( A⁻ ) = 1 - P( A)</em>
= 1 - 0.45
= 0.55
<u><em>Final answer</em></u>:-
<em>The probability of the complement of Event A = 0.55</em>
Answer:
0.2278
Step-by-step explanation:
z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation
z => 72 - 80/4
= -2
Probability value from Z-Table:
P(x ≤ 72) = P(x = 72) => P(x < 72)
0.02275
Approximately =>0.2278
