Answer:
0.913716
Step-by-step explanation:
Given a normal distribution :
Mean, x = 1050
Standard deviation, σ = 375
The Zscore = (x - mean) / σ
Zscore = (675 - 1050) / 275
Zscore = - 1.364
The probability :
P(Z > - 1.364)
P(Z > - 1.364) = 1 - P(Z < - 1.364) = 1 - 0.086284
P(Z > - 1.364) = 0.913716

Answer:
Probability = 0.23
Step-by-step explanation:
Probability of picking it choosen those at random without replacement =Pr(ace) + Pr(spade)+Pr(a four)
Probability = 4/52 + 4/52 + 4/52
Probability= 3(4/52)
Probability = 0.23
