A spinner has 10 equally sized sections, 5 of which are gray and 5 of which are blue. The spinner is spun twice. What is the probability that the first spin lands on gray and the second spin lands on blue? Write your answer as a fraction in the simplest form.

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur. Mathematically,

Probability = Expected outcome/Total outcome

If the spinner has 10 equally sized sections 5 of which are gray and 5 of which are blue, the total outcome will be equal to 10.

The probability that spinning lands on blue = 5/10

The probability that spinning lands on gray = 5/10

The probability that the first spin lands on gray and the second spin lands on blue is 5/10*5/10 = 25/100

25/100 = 1*25/(4*25) = 1/4

Hence, the probability that the first spin lands on gray and the second spin lands on blue in its simplest form is 1/4

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)
