a computer program consists of two blocks written independently by two different pro- grammers. the first block has an error with probability 0.2. the second block has an error with probability 0.3. if the program returns an error, what is the probability that there is an error in both blocks?
Using the probability of independent events, it is found that there is a 0.06 = 6% probability that there is an error in both blocks.
What is probability?Mathematical representations of the likelihood of an event occurring or of a proposition being true are dealt with in the area of probability.The probability of an event is a number between 0 and 1, where 1 denotes certainty and 0 normally denotes impossibility.Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty.We can only forecast how likely an event is to occur using it, or how likely it is to occur.P (E) = Number of positive results and The formula for determining an event's probability uses the total number of possible outcomes. Probability is hence the possibility that a random occurrence will take place.If two occasions, A and B, are separated, the probability of both happening is the expansion of the probability of each ensuing, that is:
P(A ∩B)= P(A)P(B)
In this problem, the possibilities are:
Event A: Error on the first block, with 0.2 probability, hence
P(A)=0.2
Event B: Error on the second block, with 0.3 probability, hence
P(B)=0.3
The probability that there is an error in both blocks is:
P(A ∩B)= P(A)P(B)= 0.2(0.3)=0.06
0.06 = 6% probability that there is an error in both blocks.

Approximately 6 videos, each has 60 minutes duration and 3.9 GB capacity can be stored on a 25GB optical disk.
In this question, it is asked to calculate how many videos can be stored on a 25 GB optical disk. So, the calculation is given below:
The optical disk has a capacity of 25GB.
Each video's required storage is 3.9 GB which has 60 minutes in duration.
First, we calculate how many videos can be stored on an optical disk that has 25 GB capacity.
For this purpose, we need to divide the capacity of each video by the total capacity of an optical disk which is 25 GB.
So,
25/3.9 = 6.410 number of videos (~ 6 videos)
