Answer:
0.375
Step-by-step explanation:
The probability of having at least one girl out of 3 children can be calculated as;
P(1 girl, 2 boys) or P(2 girls, 1 boy) or P(3 girls)
Since the P(b) = P(g) = 1/2
Then the probability at any point in time is 1/2 * 1/2 * 1/2 = 1/8
So we have ;
1/8 + 1/8 + 1/8 = 3/8 = 0.375
Answer:
15, 17, 19
Step-by-step explanation:
let the first odd number be n then the next 2 are n + 2 and n + 4 , then
n + n + 2 + n + 4 = 51
3n + 6 = 51 ( subtract 6 from both sides )
3n = 45 ( divide both sides by 3 )
n = 15
Then
n + 2 = 17 and n + 4 = 19
The 3 consecutive odd numbers are 15, 17, 19
