Happy Monday. Let's see if you can get your brain working after the pre-4th of July weekend fun you had.

Two questions for you this morning:
1 - What is the probability that the first business day of a month is a Monday?

2 - What is the greatest dollar value in coins you can have in your hand without being able to make change for a dollar?

1 - no probability need for practical purposes, available by checking calendar

2 - theoretically, unlimited if you have silver dollars.

1. you're thinking about ir tompletely wrong.
2. if you have two silver dollars, you have change for a dollar bill...so that doesn't hold water.

My my, they've trained us well

20% = (business days are not Saturday or Sunday for most non-banking people), so the first business day being a Monday has a chance of 1 in 5 or 20%.

\$1.09 = 3x \$.25, 3x \$.10, 4x \$.01

2:

\$1.19

3x quarters; 4x dimes; 0x nickels; 4x pennies

Kheric - think again.

I am surprised no one has got #1 correct. Pretty easy math. When you see the answer you'll kick yourself.

9 dimes
1 quarter
4 pennies

--> \$1.19

1 - 38.1%

For most months, probability is 3/7 (if the 1st is Saturday, Sunday or Monday, first business day is Monday).

In January, New Years falling out on Friday or Saturday is good; if it falls Sunday or Monday, Monday is a holiday. 2/7.

In September, 0/7, since first Monday is Labor Day.

Take average of 1x(0/7), 1x(2/7), 10x(3/7)

38.1%

1) 3/7

2) no answer. Take 3 quarters, and you can add as many dimes as you want without making a dollar.

Never mind, my second answer is definitely wrong.

Now that I think about it, this is too obvious. The answer is about 43%. The only explanation is if you count the first day of the month as a Saturday or Sunday, then those "count" toward the first business day being on Monday, so 3 of the 7 days in a week could make Monday the first business day. I just took too small of a sample earlier.

Regarding the extra dime...yep. Extra dime. Not sure why I didn't write that as I threw out the 4 dimes theory earlier in my head and accepted 3. Ah well.

3/7.... Monday, Saturday and Sunday all basically equal a Monday...
