Mrs Mullins is using a random number generator to call students. It uses the numbers 1-30. What is the probability that it will pick the number 8 two times in a row

1 in 900, or 0.00111, or 0.11%

Step-by-step explanation:

Assuming that the likelihood of each number being called is equal, there is a 1 in 30 chance that the number 8 will be called each time. The probability that 8 is picked twice in row is given by:

There is a 1 in 900 chance, or 0.00111, or 0.11%.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
