So if 123 x 47= 5781, 123 x 0.47= 57.81, why? because its exactly like dividing the number by 100, instead of dividing in the end, we divided one of the multipliers :)
Answer:
26 bc it is equall
Step-by-step explanation:
Answer:
0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.
Step-by-step explanation:
For each donor, there are only two possible outcomes. Either they have type O blood, or they do not. The donors are selected randomly, which means that the probability of a donor having type A blood is independent from other donors. So we use the binomial probability distribution to solve this problem.
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.
In New York City, 45% of all blood donors have type O blood.
This means that
.
Find the probability that 5 randomly selected blood donors in NYC all have Group O blood.
This is
when
. So


0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.
Wouldnt that just be 75x2? bc if so then
The answer is:
75x2=150+ 850=1000
