Hi, I'm a college freshman conducting a sociological research and I'm trying to get a grasp on basic statistics, specifically probability. I never did it in highschool. I learn well by examples, so can anyone please solve these samples for me with explanations? I'd be very thankful!
a.,
Two dice are rolled, find the probability that the sum is equal to 5.
b.,
A die is rolled and a coin is tossed, find the probability that the die shows an even number and the
coin shows a head.
c.,
On a lottery ticket players have to mark five numbers out of the numbers 1, 2, 3, …, 90. At the weekly
lottery show, the five winning numbers for that week are publicly drawn.
What is the probability that the first 2 numbers will be less than 45.
