    I CANT DO THESE TWO QUESTIONS PLEASE ANYONE SAVE ME 😭

    pascal triangle represents the values of nCr. Once you understand how it is defined the questions are straightforward. You need to then make use of the formula probability = num_permutations*probability_of_single_events. Make sure to understand why this formula holds.

    Geometric Series Q

    This is not correct. You have changed series. Also the formula for geometric series has not been applied correctly. You should power to n. Also number of terms are now n-1 since you have remove the 1.

    Geometric Series Q

    a is always the first term in the series. So therefore a = 1. r is defined to be the ratio of successive terms. So r = 2(0.9)/1 = 2(0.9)
