Aresearcher determines the probability that a research study will reveal something new is p = 0.80. what is the probability that the study will reveal something new or not reveal something new?
0.80
0.64
1.00
0.16

The probability that the study will reveal something new or not reveal something new would be equivalent of adding the probability of these two events together.

P(reveal something new) + P(not reveal something new)= 0.8+ 0.2= 1.0

Hence this shows that these two events encompass all the possible outcomes of the research study, which is accurate as the study will either reveal or not reveal something new, there is no other possible outcome other than these two outcomes.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
