Write an expression to represent the sum of the numbers in the nth row of pascal’s triangle. a. n/2 c. 2n b. n² d. 2n select the best answer from the choices provided a b c d

Choose from your options option where is given

Step-by-step explanation:

Pascal's triangle is a number triangle with numbers arranged in staggered rows such that each n-th row consists of n+1 binomial coefficients.

The sum of the numbers in the n-th row of Pascal’s triangle is

This sum for every n is always equal to

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
