First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.

Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.

To find them combined, multiply:

1/2 * 1/10
1/20
0.05

Hope this helps!

BartSMP [9]

Hello there!

$65-4^2 (10-2)+37 \\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓↓

I gave you a hint.

You had to used PEMDAS.

P-Parenthesis

E-Exponents

M-Multiply

D-Divide

A-Add

S-Subtract

First you had to calculate with parenthesis first.

$65-4^2(10-2)+37$

$65-4^2*8+37$

Then you calculate with exponents.

$4^2=4*4=16$

$65-16*8+37$

You had to multiply and divide you had go to left to right.

$16*8=128$

$65-128+37$

Then you add or subtract you had go to left to right.

$65-128+37=-26$

$=-26$

Answer⇒⇒⇒⇒⇒⇒=-26

Hope this helps!
