Answer: 41/365
Step-by-step explanation:
The probability of being born in May is 31/365 (May has 31 days and there are 365 days in a year).
The probability of being born on the 30th of the month is 11/365 (11 months have at least 30 days). However, since we have included May 30 in our MAy probability, we need to use the probability of 10/365.
Add the two probabilities together, and the probability of being born in May or on the 30th is 31/365 + 10/365 = 41/365.
Answer:
3/7
Step-by-step explanation:
Use Y2-Y1/X2-X1
So, 7+2/7+14=9/21
9/21 can be simplified so divide both by 3 which leaves you with 3/7
Answer:
52 adult tickets and 4 children's tickets
Step-by-step explanation:
596=11a+6c
Multiple answers are possible:
Let's use guess and check with (52,4)
596=572+24 when x=54 and y=4
52 adult tickets and 4 children's tickets being sold can total to $596
