Probability

Solve column 1


@AjayChowdhury
check if any mistake in D

@sanketbiradar A part is done wrong. It is said square of an even integer. So you only consider numbers ending in 0,2,4,6,8 .. their squares end in 0,4,6,6,4 respectively. so prob(p) of last digit being 4 is 0.4 and 5p = 2

@athakur yes๐๐ป,I have solved for all integers but the concept is same

@sanketbiradar part D is right. Pls see the answer
