What is the probability of even numbers selected from 1 to 10?
there are 5 even numbers (2,4,6,8,10), so the probability of choosing an even number is 5/10. we get probability of (b) is equal to 5/10.
What is the probability that a positive integer not exceeding 100 is divisible by 5 or 7?
What is the probability that a positive integer not exceeding 100 selected at random is divisible by 5 or 7? There are: ⌊100/5⌋ = 20 positive integers divisible by 5. ⌊100/7⌋ = 14 positive integers divisible by 7.
How do you find the square of 43?
To find the side of the land, we will have to find the square root of 43. The square root is √43 = 6.557.
How many perfect squares are there between 5 and 50?

What is the probability that a product will be faulty?
If we do the trial again with a different number of products, we can expect 2\% of them to be faulty. This is a theoretical probability which can be worked out mathematically. P (A) = Number of ways the event can occur / The total number of possible outcomes
What is the probability of getting a six in probability?
If the event is A and the probability of A occurring is P (A), then for N trials, the expectation is: For the simple example of a dice throw, the probability of getting a six is 1/6. Remember, the expectation is not what will actually happen, but what is likely to happen.
What does it mean when the probability of an event is 0?
A probability of 0 means that an event will never happen. A probability of 1 means that an event will definitely happen. In a trial, if event A is a success, then failure is not A (not a success) Events are independent when the occurrence of one event doesn’t affect the probability of the other event.
How do you calculate the probability of getting a 7?
P (getting a 7) = 0 / 6 = 0 (there are no ways the event 7 can occur in any of the 6 possible outcomes) Empirical probability of failure = P (failure) = 999/1000 = 0.999 A probability of 0 means that an event will never happen. A probability of 1 means that an event will definitely happen.
