PLEASE HELP WILL MARK BRAINlIEST LOTS OF POINTS ON THE LINE a venn diagram shows the number of students who passed their examination in french [F] and German [G]. the number of students who dint pass either is b.

french=17 German=11 both=19

a. what is the value of b is the total students is 55
b. 1 of the 55 students is chosen at random, as a fraction what is the probability that this student:
a. passed both french and German
b. passed exactly 1 of these 2 subjects

see below

Step-by-step explanation:

A

Add the students who passed french, german, both

add 17+19+11 = 47

Subtract this from 55 to get b

b = 55-47 =8

b =8

B

P( passed french and german)

    = number that passed french and german / total

    = 19/55

P( french or german) =

  = number that passed french or german / total

    = (17+11)/55 =28/55

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
