Basically there are 180 days in a school year so if a school buss is late 24 times in 30 days it will be late 168 times in a school year not counting the last days which will be exactly 173 late buses in a whole year .
Hope this helped :)
there are 52 cards in a deck, 12 of those cards are "face cards", so the remaining are number cards, namely 40.
52 = sample space
40 = favorable outcomes
P(number card | number card) = p(number) * p(number)
so the first time we pull one, there are 52 cards, the probability of a number card is 40/52, or 10/13, and we don't put it back in the deck.
the next time we pull another card, the cards are no longer 52 total, we pulled one out, they're only 51, namely 51 = sample space, and the number cards if we really pulled out before, are no longer 40, are 39, namely 39 = favorable outcomes.
probability of getting a number card the second time? 39/51 or 13/17.
Professor Dan Healy, one of my Engineering instructors back in prehistoric times, had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it. Here is Prof. Healy's method.
For a few moments, call the square root of 5 by the name "cow".
cow - x = 4 . Solve this equation for 'x' :
Add 'x' to each side of the equation: cow = 4 + x
Subtract 4 from each side: cow - 4 = x
Now, we can put the real value back in place of 'cow' : <u>√5 - 4 = x</u>
That right there is a perfect solution. But If you absolutely need to
know the number, then grab your calculator:
√5 = 2.2361 (rounded)
x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)
