You take the total number of picture and multiply it by .12, which will get you the total number of black and white photos only.
600(.12)= 72
Answer:
The probability that exactly two have flaws is P (x=2) = 0.2376
Step-by-step explanation:
Here
Success= p= 0.15
Failure = q= 0.85
total number= n= 8
Number chosen = x= 2
Applying the binomial distribution
P (x=x) = nCx p^x(q)^n-x
P (x=2) = 8C2 0.15 ²(0.85)^8
P (x=2) = 0.2376
The success is chosen about which we want to find the probability. Here we want to find the probability that exactly two have flaws so success would be having flaws therefore p = 0.15
9 and 1/2 is a mixed number
Answer:
c : they will have both saved 97
Step-by-step explanation:
7*6 = 42 + 55(base) = 97
12*6 = 71 = 25(base) =97
