What is the upper limit of the class interval 30 – 40?
Upper limit is the highest number of the interval. Hence upper limit is 40 in the interval 3040.
Which class has the lowest frequency?
What is the size of the class interval?
Class interval refers to the numerical width of any class in a particular distribution. It is defined as the difference between the upperclass limit and the lower class limit. Class Interval = UpperClass limit – Lower class limit.
Which two classes have the same frequency?
What is the lower limit of the class interval 40 – 50?
Lower limit is the least number of the interval. Hence 40 is the lowest limit.
Which class has the highest frequency?
When a die is thrown, total number of possible outcomes is ______.
When a coin is thrown, total number of possible outcomes is ______.
Two dice are thrown, find and number of outcomes.
We know that in a single thrown of two die, the total number of possible outcomes is (6 × 6) = 36. Let S be the sample space. Then, n(S) = 36
There are 2 Red, 3 Blue and 5 Black balls in a bag. A ball is drawn from the bag without looking in to the bag. What is the probability of getting a nonred ball?
Non  red ball = 8
Probability = No of non red balls/Total no. of outcomes
= 8/10 = 4/5
There are 2 Red, 3 Blue and 5 Black balls in a bag. A ball is drawn from the bag without looking in to the bag. What is the probability of getting a red ball?
There are 2 Red, 3 Blue and 5 Black balls in a bag. A ball is drawn from the bag without looking in to the bag. What is the probability of getting a blue ball?
There are 2 Red, 3 Blue and 5 Black balls in a bag. A ball is drawn from the bag without looking in to the bag. What is the probability of getting a black ball?
There are 2 Red, 3 Blue and 5 Black balls in a bag. A ball is drawn from the bag without looking in to the bag. What is the probability of getting a nonblack ball?
There are 2 Red, 3 Blue and 5 Black balls in a bag. A ball is drawn from the bag without looking in to the bag. What is the probability of getting a nonblue ball?
Total out comes are=2+3+5=10
So, Probability of getting a non blue ball is = 7/10
