Good. Learning basic probability. The OR rule.
firstly, there are 4 jacks in a pack of 52.
but only 1 jack of clubs, so 
p(jack of clubs) = 1/52
secondly, there are 13 diamonds, and only one two of diamonds. so, 
p(two of diamonds) = 1/13.
The OR rule (sum)
P(jack of clubs OR two of diamonds)= (  1/52 + 1/13) = 0.096

Well, there are 52 cards. The probability of picking 2 out of 52 cards would be:

2/52!   Or in simplest terms, 1/26.

Answer:

When you divide a positive number (such as 1,000) by a number greater than 1 (such as 5), the answer must be smaller than the number you started with. The answer must be smaller than 1,000. 2,000 is greater than 1,000, so it cannot be correct. The correct quotient is 1,000/5 = 200.
