The letters needed to spell "probability" are placed in a bag. P, R, O, B, A, B, I, L, I, T, Y What is the probability that a "B" will be drawn from the bag
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
The letters needed to spell "
P, R, O, B, A, B, I, L, I, T, Y
What is the probability that a "B" will be drawn from the bag?
A. 1/5
B. 1/11
C. 1/10
D. 2/10
Let,
N is the total number of alphabets in the bag.
n(B) is the number B alphabet in the bag.
The "probability" word has 11 alphabets. So, N=11
There are two "B" alphabets in the bag. So, n(B)=2
