We have that the probability of Janice rolling a 2 or 5 on her 7th toss of the dice is

From the question we are told that
Janice rolled either a 2 or a 5 on the last 6 rolls of the die
Janice rolling a 2 or 5 on her 7th toss of the dice

Where

Janice roll the standard die 7th time the probability of getting 2 or 5 is

Answer:
B. Commutative
Step-by-step explanation:
He can do that because it's a sum
2km=2 kilometer
kilo=1000 so 2 km=2000m
25m
2500cm
cm=centimeter=1/100 of a meter
so
2500cm=25m
mm=milimeter=1/1000 meter
so
3000mm=3m
so the longets is obviously 2000m or 2km
If the E(X) = 1 then that means it has a 100% which is incorrect.
Each
block has an equal probability to contain the error so 1/3 because you
choose 2/6.
