2 numbers are 0.45 and 0.4. 0.4 would equal 2/5 in simplest form. 0.45 in simplest form is 9/20. hope this helps.
76 or 77. 2/3 times x/115. 2 times 115 is 230. 230 divided by 3 is 76.6666666667.
Answer:
A. Probability = 0.02
B. This is in a cumulative frequency table in the attachment I added
Step-by-step explanation:
A. We have these following probabilities
Prob(X=0) = 0.05
Prob(x= 2) = 0.30
Prob(X = 4) = 0.50
Prob(X < 2) = Prob(X=0) + prob(X=1)
0.18 = 0.05 + prob(X=1)
prob(X=1) = 0.13
A. Prob(x = 3)
= 1 - (0.05 + 0.13 + 0.30 + 0.50)
= 0.02
Probability of buying only 3 times = 2%
B. The cumulative frequency is in the attachment.
