Answer:
Step-by-step explanation:
First we will find the probability of selecting five cards out of pack of cards
Probability of selecting five cards is equal to
On expanding we get
straight high card 
means five cards with values lesser than but adjacent to it are
there are four card for each number
Hence, probability of choosing five cards is equal to
Probability of getting a straight with high card 9 is equal to
-80%(-.8),-.75,-6/8(-.75),-3/5(-.6)
I use it all the time, but as my profession is engineering, mathematics is integral in my everyday life. I usually do it when evaluating for the magnitude of vector force components. Usually in 2D space, so Pythagorean theorem is quite useful.
Answer:
1/5
Step-by-step explanation:
We assume the events are independent, so the probability of the joint event is the product of the probabilities of the individual events.
P(Y or W) = 2 letters of 5 = 2/5
P(easy) = 1 of 2 kinds = 1/2
The product of these is ...
P((Y or W) and (easy)) = (2/5)(1/2) = 1/5
_____
In both cases, we have to assume that each of the possible outcomes is equally likely.
