Winona rolls a 10 -sided die, numbered 1 through 10. What is the probability that she'll get an odd number or a 4?
6-10
6 out of 10 :D
count the number of odd numbers from 1 to 10. Take that number and divide it by the total amount of numbers on the die. That's the probability she'll get an odd number. To this, add the probability she gets a four. There's only 1 four on the die so it's 1/total amount of numbers
Lmaooo Liviahhhh !
Lmao Falon! O.o
haaaaaaaaaaa
Hhahahahaha Weird
I No ! Cheater !
Lol. Shhhhhhh! |dw:1346375866108:dw|
Determine the number of odds between 1-10 (1, 3, 5, 7 &9). Then determine the number of 4's between 1-10 (4 - only 1). Add the number of odds and the number of 4's (1, 3, 5, 7, 9 & 4 = 6 possibilities) and divide by the total possible results(10). Therefore, your answer is 6/10 or 60%.
