Answer:
The probability that a person is younger than 50 given that she uses onling banking is 1.5%
Step-by-step explanation:
The survey indicated that 50% of adults conducts their banking online.
P(online banking customers) =1/2
Of the total number of customer that bank online, the survey stated that 20% of them are younger than 50 years.
P(customers younger than 50 yrs) =1/5
Out of the 20% than are younger than 50, we were told that 15% of them conduct online banking.
P(younger than 50 online banking customer) =3/20
Therefore the the probability that a = person is younger than 50 given that she uses online banking is P = 3/20*1/5*1/2 =17==3/200 = 0.015 =1.5%
The probability that she is younger than 50 does not increase or decrease with additional information, it only makes it clearer.
12, this is because 3 *4 =12 and those are your denominators.
Answer:
Option D. 36°
Step-by-step explanation:
we know that
The sum of the exterior angles of a polygon must be equal to 360 degrees
In a regular polygon all the exterior angles are congruent
so
To obtain the measure of each exterior angle divide 360 by the number of sides
In this problem the number of sides is 10
360/10=36°
Answer:
here
Step-by-step explanation:
it is basically a sector , use the area formula i.e.
[(theta)/360]*πr^2
Three equivalent ratios:
16:20
24:30
32:40
