Atest was given to a group of students. the grades and gender are summarized below a b c total male 5 18 8 31 female 9 7 16 32 total 14 25 24 63 if one student is chosen at random from those who took the test, find the probability that the student got a 'c' given they are male.

Pr. (male) = 0.49

Explanation:

                  A                   B                   C                   TOTAL

male           5                   18                   8                   31

female        9                   7                   16                   32

TOTAL        14                 25                 24                  63  

Now to find the probability that the student got a 'C' given they are male, we need to know the total numbers of males(i.e no of required outcomes) which = 31

also the total number of the group of students(i.e total no of possible outcomes) = 63

∴ Since Probability =

we have Pr (male) =  

=0.49

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
