Answer:
160 children, 112 boys and 48 girls.
Step-by-step explanation:
You can translate this into two equations:
g = 3/7 * b
g+64 = b
Then fill in one in the other and simplify:
3/7 b + 64 = b =>
4/7 b = 64
b = 64 * 7/4 = 112
g = 112 * 3/7 = 48
Answer:
120
Step-by-step explanation:
80 represents the 2
Do 80 / 2 to get one 80 /2 = 40
So 1 would equal 40
Do 40 * 3 = 120 to get the three which represents the number of adults
Answer: Our required probability is
Step-by-step explanation:
Since we have given that
Number of red envelopes = 3
Number of blue envelopes = 3
