Q1: Basically you need to find out pairs whose product is 99.
So we have 99=1*3*3*11.
So 09/11, and 11/09 are two dates which satisfy your condition.
Q2: since there are 2*2*2=8 ways how 3 coins will land, and only 3 ways how exactly 2 coins show heads, the probability is 3/8.
Q3: 50cents*7, 20cents*1, 10cents*2, 5cents*1. That means at least 11 coins to satisfy your conditions.

This is called cheating, you are in 7th grade and should do your own work, I will give you a head start on the questions though cuz I'm a nice guy.
1.#<13 * #<32=99 see how many possibilities
2.list all the possibilities, ten see how many satisfy your conditions
3.bad grammer, but, 3.95-(0.05+0.1+0.2+0.5)=x, then, find the least number of coins that could make up a x and add 4

Stop cheating, also stop point gaming. Do your own homework. Spend the time you are checking this and actually try to learn, so that you gain some knowledge and some intelligence.

You're not asking for help, you're asking for people to do the work for you (and rather rudely, telling them to show work!). That is called cheating.
If you would like to ask a specific question about how to do it yourself, or have someone check your work for you, I'm sure someone will be happy to help you.
