The blood groups of 200 people is distributed as follows: 50 have type A blood,
65 have B blood type,
70 have O blood type and
15 have type AB blood.
If two people from this group is selected at random, what is the probability
that they will have B or O blood types? Write your answer as percentage.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
