Jacob stood in a line to pick up a souvenir postcard at the museum all the postcards were blue, white, or green with a picture of a fish, insect, or bird there was an equal number of each type of postcard what is the probability that jacob was randomly handed a green postcard with a fish on it a.) 1/9 b.) 1/3 c.) 1/6 d.) 1/2

1/6

Step-by-step explanation:

just trust me on this

A.) 1/9

Step-by-step explanation:

There are 9 cards. 3 fish cards of each color, 3 insect cards of each color, and 3 bird cards of each color. A green fish card would have a 1/9 chance of being picked

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

2
