Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × 
× 
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × 
× 
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × 
+ 15C5 ×
P = ( 15C8 + 15C5 )
P = ( ( 
) + ( 
) )
P = ( 6435 + 3003 )
P = ( 9438)
P = 
( 4719)
P = 
P = 0.29
Step-by-step explanation:
as in the other problem, the table describes mutually exclusive attributes.
so, we can simply sum the numbers up to get the total number of students :
3+9+2+16 = 30 students.
so, when picking a random student, we have 30 possibilities.
now, how many of those 30 have the desired attributes (to have a brother AND a sister) ?
I see 3 in the table.
so, the probability to pick a student that has a brother and a sister is
3/30 = 1/10 = 0.1
