Answer:
2/7, 0.005
Step-by-step explanation:
Question 1:
In a leap year (366) days, 364/7 = 52 are complete weeks.
The extra day can be Monday, Tuesday,...…, Saturday, Sunday.
So, the probability of getting 53 Sundays in a leap year = 2/7
Question 2:
no. of prize tickets =5
no. of black tickets =995
total no. of tickets =1000
Probability of his winning prize
= no. of favourable outcome / total outcome = 5/1000
= 0.005
