Answer:
1/3
Step-by-step explanation:
The probability of a student winning is 1/4.
The probability of a prize being selected is 1/3.
The probability of Gail winning a scarf is 1/4 × 1/3 = 1/12.
The probability of Simon winning is 1/4.
The probability of either is 1/12 + 1/4 = 1/3.
Answer:
As 2.551 < 3.84 therefore we reject H0.
As 44.803 > 4.46 so we accept null hypothesis.
Step-by-step explanation:
The answer is attached.
There are three judges so v1 = 3-1= 2 and v2 = (4*2)= 8
There are five gymnasts so v1 = 5-1= 4 and v2= (4*2)= 8
For alpha = 0.05 we find the value of F1 and F2 from the table.
Answer:
0.60
Step-by-step explanation:
Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
The probability of a mistake on at least one page is 1 minus the probability of making no mistakes.
P(at least 1) = 1 − P(none)
P = 1 − ₁₁C₀ (0.08)⁰ (0.92)¹¹⁻⁰
P = 1 − (0.92)¹¹
P = 0.60
Answer:Step-by-step explanation:
so if you buy 2 jumpers it will be the cost of 1
and 30% of 50 is 15 so 15 + 15 = 30 plus 45 =
75
