What is the probability of rolling an even number on a number cube containing numbers 1 through 6? *

or 50%

Step-by-step explanation:

Cube has 6 sides = 3 odds and 3 even

probability is found using

which is

1/2 = 50%

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
