MATHEMATICS PROBLEM SOLVER

It is a site for parents, students and teachers. This site can help O-LEVEL or GCSE secondary school students in mastering mathematics subject. It intends to involve the learners by making them follow up the examples before they can do questions on their own at the TRY THIS.... section. There are some videos, tests, quizzes and past examination questions. Learning the examples will ultimately give students the required confidence in solving various questions in mathematics.

PROBABILITY 11

A card is chosen at random from a deck of 52 cards. It is then replaced and a second card is chosen. What is the probability of choosing a queen and then an eight?

solution

P(queen)	=	4
P(queen)	=	52

P(8)	=	4
P(8)	=	52

P(queen and 8)	=	P(queen)	·	P(8)

	=	4	·	4
	=	52	·	52

	=	16
	=	2704

	=	1
	=	169

Hence probability of choosing a queen and then an eight is ¹/169
