4/20 students say S.S. is their favorite
75% say PE is their favorite
you need to get them in the same conditions, one is fraction, and one is percent
4/20= ?% /100 4 __ cross multiply on paper
20 100
4x100= 400/20=20
20% say s.s. is their favorite
20% is smaller than 75%
expresson: 4
20< 75%
We have been given that the probability of a computer containing a virus P(v) is 0.15 and probability of computer containing a worm P(w) is 0.05.
We are also told that probability of computer containing either virus or worm
is 0.17.
(a) To find out the probability that the computer contains both a virus and a worm we will use probability formula,

Now let us substitute our given values in this formula.


Therefore, probability that that the computer contains both a virus and a worm is 0.03.
(b) To find out the probability that the computer contains neither a virus nor a worm we will subtract the probability of computer containing both virus and worm from 1.


Therefore, probability that the computer contains neither a virus nor a worm is 0.83.
