Explanation / Answer
Q1)
since each flip is unconnected to the previous flip implies that each flips are independent
This is an example of events that are Independent.
Q2)
In probability theory, an event is a set of outcomes of an experiment (a subset of the sample space) to which a probability is assigned.
so answer is Event
Q3)
no of odds numbers in a die = no of even numbers in a die = 3
probability of getting an odd number on a fair die = 3/6 = 1/2
probality of getting a tail on flip of a coin = 1/2
probability of getting an odd number on a fair die and a tail on a coin flip = (1/2)*(1/2) = 1/4
Q4)
no of numbers less than three on a fair die = 2
probability of getting a number less than three on a fair die = 2/6 = 1/3
probability of getting a number less than three on a fair die and tail on a coin flip = (1/3)*(1/2) = 1/6
Q12)
no of cards in a deck of cards = 52
no of 2 and a face card in a deck are 0
probability of choosing a 2 and a face card from a deck of cards =0/52 = 0.00
