on even number wos octuolly rolled using the toble?
3.) If you roll o number cube 36 times, how marry times would
you expect to roll the number one?
4.)
How mony times did you octuolly roll the number one in the experiment?
5.) Whot
is the theoreticol probobility
for rolling
o number greater than 4?
6.) Whot wos the dxperimentol probobility of rolling
7.) Whot
8.)
If
is
o cor
o number greater thon 4?
the differencebetween theoretical ond experimental probobility?
foctory checks 360 cars ond I of them hsve defects, how many will hove defects
out of Q6A?
9.)
If
NOT
o cor foctory checks 320 cars and 12 of them have def ects, how mony out
have defects?

10.) You plant 3O Africon violet seeds ond 9 of them sprout. Use experimental probobility to
predict how mony will sprout if you plont 20 seeds?
11.) If you ore picking o number between 1-20 whot is the probobility thot you will pick o
number greater thon 14 or less thon 4?
12.) Tf you ore picking o number between 1-20 whot is the probobility thot you will pick on even
number or o multiple of three?
13.) If you ore picking a number between 1-20 whot is the probobility thot you will pick o
multiple of two or o number greoter thon 15?
