The greatest amount is 45 and they would have bought 3 boxes
<h3>
Answer: 5/19</h3>
=========================================================
Explanation:
There are A = 10 red cards out of B = 10+10 = 20 cards total.
A/B = 10/20 = 1/2 represents the probability of picking a red card.
After that card is selected, there are C = 10 black cards out of D = 20-1 = 19 cards left. The fraction C/D = 10/19 represents the probability of picking a black card where we did not put the first red card back.
Multiply the two fractions we found.
(A/B)*(C/D) = (1/2)*(10/19) = 10/38 = 5/19 is the probability of getting the first card that is red and the second card that is black.
Answer:
36 days
Step-by-step explanation:
Cole's watch runs fast. In 1 day, it gains an hour. So in 12 days, it gains 12 hours and is correct again.
We find the multiples of
Multiples of 12:
12, 24, 36, 48, 60, 72, 84
Note that
1 hour = 60 minutes
12 hours= x
Cross Multiply
x = 12 × 60
x = 720 minutes
Julio's watch also runs fast. In 1 day it gains 20 minutes.
Hence, 720 minutes/20
= 36
Therefore, to calculated how many days will their watches next show the correct time together we use LCM method
We find the Multiples of 12 and 36
Multiples of 12:
12, 24, 36, 48, 60
Multiples of 36:
36, 72, 108
Therefore, LCM = 36
The number of days that their watches next show the correct time together is 36 days
