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:
-0.6309
Step-by-step explanation:
Using the change of base formula,
Log 1/2 to base 3 = Log1/2 ÷ Log 3 = Log 0.5 ÷ Log 3
Log 0.5 = -0.3010
Log3 = 0.4771
Log 0.5 ÷ Log 3 = -0.3010 ÷ 0.4771 = -0.6309
