Answer:
factors ?
Step-by-step explanation:
Answer:
both watered on the same day, If we multiply 18 by any number such as 2,3,4,5 we can find the next soonest date that they will both be watered on. 18*2,3,4,5 30,2,3,4,5
18*2,3,4 are not multiples of 30, 18*5 is 90
30*2 is not a multiple of 18, 30*3 is 90
Now we know the next closest date they will be watered again is 90 days from now.

Answer:
The answers to the questions are;
(a) P(At least 1 defective)
= 0.9883.
(b) P(At least 1 defective)
= 0.6409.
Step-by-step explanation:
There are 110 cards and 20 defectives.
a) The probability of at least one defective is given by
P(At least 1 defective) = 1 - P(0 defective)
P(0 defective) = 20C0 × (90C0)/(110C20) = 0.0116
1 - 0.0116 = 0.9883
b) For a set of 110 boards that has 5 defective and 105 non-defective
P(At least 1 defective) = 1 - P(0 defective)
P(0 defective) = (20C0)(90C5)/(110C5) = 0.35909
1-0.35909
= 0.6409
