To identify:The probability that you will answer all three correctlyA multiple choice test has four choices for each answer. Suppose you make a random guess on three of the ten test questions.
*Is each guess a dependent event or an independent event?
*What is the probability that a random guess on one question will yield thecoorect answer?
The probability
Given information:
A multiple choice test has four choices for each answer. Suppose you make a random guess on three of the ten test questions
Explanation:
Consider the given information.
Determine the probability that a multiple of 4 or 5 is chosen from 1 to 100
Multiple of 4 from 1 to 100
Since here last term of the series is 100 so by using formula of nth term of AP.
So, number of multiple of 4 is 25
Multiple of 5 from 1 to 100
Since here last term of these series is 100 so by using formula of nth term of AP.
So, number of multiple of 5 is 20
Therefore
Number which are multiple of both 4 and 5 are
20,40,60,80,100
So, there are 5 number that are divisible by both 4 and 5
So
Therefore
Hence
