If the last number is 1 -> 21 <50
if the last number is 3 -> 63 > 50 OK
if the last number is 5 -> 105 which is not a two digits number
if the first number is 4 -> 42<50
if the first number is 6 -> we get 63 again
if the first number is 8 -> we get 83 which is not odd
63 is the only answer
Answer:
<h2>
0.7</h2>
Step-by-step explanation:
A' is everything what is not A
So:
A' = {9, 10, 11, 12, 13, 15, 16}
Number of ways it can happen: |A'| = 7
Total number of outcomes: |Ω| = 10
Probability of an event happening:

51 - 3 = 48
48 / 4 = 12
the answer is 12 days
hope it helped :)
