Answer:
Hendecagon
Step-by-step explanation:
a hendecagon has 11 sides
It is given that getting boy or girl is equally likely. The chance of getting boy or girl on birth is 1/2
P(Boy) = P(Girl) =0.5
If a couple plans to have 8 children then probability of getting at least one girl is
P(Al least one girl out of 8 children) = 1 - P(No girl in 8 children)
= 1 - P( Getting all boys in 8 children)
= 1 - (0.5)^8
= 1 - 0.0039
P(At least one girl out of 8 children) = 0.9961
The probability of getting at least one girl out of 8 children is 0.9961.
The probability 0.9961 is high enough for the couple to be very confident that they will get at least one girl in 8 children
Answer:
f = 1
Step-by-step explanation:
-x+y=3
y=x+3
2x + x + 3 =6
3x + 3 = 6
3x = 3
x = 1
-1 + y = 3
y = 4
2(1) + y = 6
2 + y = 6
y = 4
Solution: (1, 4)
