Question 6. A teacher is picked at random. 3/5 chance they are female. 36 are males. (3 marks) How many teachers are there altog

Sloan [31]

If there is a 60% chance there are female, then that must mean that 40% of the teachers are male.
If 40% of all the teachers is 36, then 20% of all the teachers are 18 in number
So, when we multiply 20% by 5 (to get 100% = all the teachers), we get:
18 x 5 = 90 teachers in total

mihalych1998 [28]

Answer:

Step-by-step explanation:

Given that a convenience store regularly buys mangoes from a wholesale dealer. For every shipment, the manager randomly inspects five mangoes from a box containing 20 mangoes for damages due to transportation. Suppose the chosen box contains exactly 2 damaged mangoes.

In the selected box 18 good mangoes and 2 damaged mangoes are there

a) Find the probability that the first mango is not damaged.

= prob of selecting 1 from any one of 18 good mangoes = $\frac{18}{20} =0.90$

b. Find the probability that neither of the mangoes is damaged. =

Prob of selecting 2 from 18 good mangoes

= $\frac{18C2}{20C2} =0.5276$

c. Find the probability that both mangoes are damaged.

= Prob of selecting 2 from 2 bad mangoes

= $\frac{2C2}{20C2} =0.005263$
