In order to solve or know the probability of having 2 girls
and 2 boys, assumed that a girl is as likely as a girl at each birth, pascal’s
triangle will be likely used. And we will be referring to the line 4 of pascal’s
triangle, which was 1 4 6 4 1. Then it
will look like this: 1 = 4 girls; 4 = 3 girls & 1 boy; 6 = 2 girls & 2
boys; 4 = 3 boys & 1 girl; 1 = 4 boys. And now for the solution in order to
get the probability of having 2 girls and 2 boys is to divided into the sum of 1+4+6+4+1.
Answer:
The missing area for both sides is 48ft²
the missing dimension is 12ft
Step-by-step explanation:
Add all the areas up
12+36+12+36=96
192-96=96
96÷2=48
48÷4=12
Answer:
Step-by-step explanation:
1 grain = 6×10⁻⁶ g
- 7200 kg =
- 7200000 g =
- 7.2×10⁶ g =
- 7.2×10⁶ ÷ 6×10⁻⁶ =
- (7.2÷6)×10⁶⁻ ⁽⁻⁶⁾ =
- 1.2×10¹² grains
