Answer:

Step-by-step explanation:





From the table given
17 people have managed care plan
9 have Traditional insurance
6 have no insurance
The probability of an event happening is given as the ratio of the number of the possible outcome divided by the total outcome.
If two balls are taken, the probability that at least one has traditional insurance
TN or TM or TT or NT or MT
where T is for traditional insurance
N is for no insurance
M is for managed insurance
the probability that at least one of two people picked without replacement has traditional insurance
= 9/32 * 6/31 + 9/32 * 17/31 + 9/32 * 8/31 + 6/32 * 9/31 + 17/32 * 9/31
= (54 + 153 + 72 + 54 + 153)/992
= 486/992
= 243/496
Answer:
Step-by-step explanation:
Given that the Acme Company manufactures widgets, which have a mean of 60 ounces and a standard deviation of 7 ounces
We know that 95% of the area lie between -2 and 2 std deviations from the mean.
i.e. Probability for lying in the middle of 95%
Z score 
Between 46 and 74 oz.
b) Between 12 and 57
convert into Z score

P(-6.86<z<-0.43)
=0.5-0.1664=0.3336
c) X<30 gives Z<-4.83
i.e. P(X<30) =0.00
