Answer:
Probability of obtaining no more than two defective tubes = 0.816
Step-by-step explanation:
The Probability of obtaining no more than two defective tubes in a randomly selected sample of 15 tubes is obtained using the binomial distribution formula: nCr × p^r × q^(n -r).
Where n is number of samples;
r is maximum number of defective tubes, r ≤ 2;
p is probability of defective tubes = 10% or 0.1
q is probability of non-defective tubes, q = 1 - p

Answer:
624%
Step-by-step explanation:
To write a number as a percetage, just multiply the decimal value by 100. In this case we have: 6.24 × 100 = 624% (answer).
➥ The easy way:
1) Shift the decimal point two places to the right:
6.24 → 62.4 → 624.

Answer:
5.40
Step-by-step explanation:
i think that's it because
if u take 150 - the one cake it will equal = 135
then u divide 135 by the 25 pies it will equal 5.40
150-15= 135
135÷ 25= 5.60
