P(A)=0.4 and P(B)=0.6. What is the probability of observing event B three times in a row?

Mathematics

Daniel [21]3 years ago

Answer:

0.216

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

The probability that an event will happen added to the probability that the event will not happen gives 1. In other words, the outcome of a probability cannot exceed 1.

The probability that an event a will happen or that another independent event  b will happen is the sum of the probability that a will happen to the probability that b will happen.

The probability that the event B will occur 3 times in a row may be interpreted as BBB and in probability, "and" is interpreted as multiplication while "or" is addition.

Pr(BBB)

= 0.6 * 0.6 * 0.6

= 0.216

What's the equation to find the midpoint of a right triangle?
Viktor [21]
The answer is 20. You have to use the Pythagorean theorem (A^2+B^2=C^2) to find the length of the hypotenuse.

32^2+24^2=C^2
1024+576=C^2
1600=C^2
Take the square root of both sides
40=C
Since the midpoint is the middle, you divide the length of the hypotenuse by 2 and get the answer (20)
