Assume a numerical class contains 41 understudies. There are 18 females (three of whom communicate in Spanish) and 23 guys (six of whom communicate in Spanish). Offer all responses as decimals to in any event two decimal spots.

1. What is the likelihood that a haphazardly chosen understudy communicates in Spanish, given that the understudy is female?

2. What is the likelihood that an arbitrarily chosen understudy doesn't communicate in Spanish, given that the understudy is male?

3. What percent of Spanish talking understudies are male?

4. In the event that somebody doesn't communicate in Spanish what is the likelihood they are female?

A study of 1,036 vacationers visiting Orlando was taken. Of those reviewed:

257 vacationers had visited the Magic Kingdom

291 vacationers had visited Universal Studios

95 vacationers had visited both the Magic Kingdom and LEGOLAND

52 vacationers had visited both the Magic Kingdom and Universal Studios

56 vacationers had visited both LEGOLAND and Universal Studios

11 vacationers had visited each of the three amusement parks

77 vacationers didn't visit any of these amusement parks

What number of sightseers just visited the LEGOLAND (of these three)?

A survey was taken of 11,695 working grown-ups matured 40-70 to decide their degree of instruction. The members were grouped by sex and by level of instruction. The outcomes are appeared beneath.

An individual is chosen indiscriminately. Process the accompanying probabilities.

(a) What is the likelihood that the chosen individual is male, given that he has a Master's certificate?

(b) What is the likelihood that the chosen individual doesn't have a Master's certificate, given that he is male?

(c) What is the likelihood that the chosen individual is female, given that she has a Bachelor's certificate?

(d) What is the likelihood that the chosen individual has a Ph.D., given that she is female?

Giving a test to a gathering of understudies, the evaluations and sex are summed up beneath

In the event that one understudy is picked aimlessly,

a) Find the likelihood that the understudy got a C:

b) Find the likelihood that the understudy was female AND got a "C":

c) Find the likelihood that the understudy was female OR got an "C":

d) If one understudy is picked aimlessly, discover the likelihood that the understudy got a 'B' GIVEN they are female:
