Answer:
The correct answer is no.
Step-by-step explanation:
If a number is a factor of another number, that means that it can be equally divided into it <em>evenly</em>.
I know that 3 x 20 = 60, and 73 - 60 = 13.
Since 3 is <em>not</em> a factor of 13, it is also <em>not</em> a factor of 73.
Hope this helps! :D
Answer:
0.36 = 36% probability that the land has oil and the test predicts it
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
45% chance that the land has oil.
This means that 
He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.
This means that 
What is the probability that the land has oil and the test predicts it?
This is
. So


0.36 = 36% probability that the land has oil and the test predicts it

Step-by-step explanation:
Given that a fair coin is tossed 11 times.
Since coin is fair probability for head p = 0.5 and q = prob for tail =0.5
Each trial is independent of the other. Hence X no of heads is binomial with 
Prob for getting 10 heads out of 11 tosses
=P(X=10)
=
