Answer:
a)n=543
b)n=1509
c)n=13573
Step-by-step explanation:
a)
c=98%,
Margin Error
but
where the confidence level is 1-α=0.98
cross multiply
where p=0.5
input the values
n=0.33
b) E=0.33
confidence level
n=(2.33/0.33)²×0.5(1-0.5)=1504
c)
1-α=0.98
cross multiply
Zα/2=2.33
p=0.5
n=(2.33/0.01)²×0.5(1-0.5)=13573

Answer : 25/51
The probability of drawing two red cards without replacement is 25/102 , and the probability of drawing one red card is 1/2 .
probability(drawing a second red card, given that the first card is red)
= Probability (drawing two red cards without replacement) divide by probability (drawing a one red card)
probability(drawing a second red card, given that the first card is red)
