Find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards.

Mice21 [21]

Answer:

1/26

Step-by-step explanation:

This is a case of joint probability. We find the two probabilities separately and then multiply the results together:

P(odd number on cube) = 3/6 = 1/2; P(7 from a deck)) = 13/52 = 1/13

Then the desired joint probability is (1/2)(1/13) = 1/26

Note that the two events here are entirely separate and independent.

Answer:

315881.53

Step-by-step explanation:

We first need to figure out how long it takes for the money to triple

let x= number of years it takes for the money to tirple

$3=(1+\frac{.04}{365})^{365x}\\log_{1.0001}3=365x\\10025.38644=365x\\27.46681216=x$

Now plug that value into the continously compounding formula

$80000*e^{27.4668*.05}=315881.5314$

Which rounds to

315881.53
