Answer:
the distance is 4
Step-by-step explanation:
18 - 2,3,6,8
24 - 2,4,6,8,12
HCF = 8
X/6 >= 9
x >= 6 x 9
x >= 54
Therefore, 60, 72 and 54 satisfies the inequality.
Answer:
B) 0.283
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
