Question

Four coins are tossed simultaneously. What is the probability that all 4 coins will land on heads? Type your answer as a percent

Answer 1

50%

Answer 2

That is incorrect

Answer 3

@LegendarySadist How so?

Answer 4

what do I do idk I thought it was close to that

Answer 5

You multiply the percentages together. What's the chance of getting a head on a coin flip?

Answer 6

50% @LegendarySadist

Answer 7

So they all have a 50% chance of being heads. Now multiply the percentages together. It might be easier to write it as \(\large \frac{1}{2}\) when you multiply them.

Answer 8

50% is wrong snuffitaly I checked it on there

Answer 9

the probability of ONE coin being heads is 50%
however, we have FOUR coins here, so we must multiply 50% 4 times

(0.5)*(0.5)*(0.5)*(0.5)

does that make a little more sense?

Answer 10

Ok thanks @LegendarySadist and @Vocaloid

Answer 11

So would it be 200?

Answer 12

um, not quite...

put in

(0.5)*(0.5)*(0.5)*(0.5) into your calculator and tell me what you get

Answer 13

* means multiply

Answer 14

\[\large \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2}\]

Answer 15

0.0625 is what i got

Answer 16

right, so convert that decimal to a percent by multiplying by 100

Answer 17

6.25

Answer 18

right, so our final answer is 6.25%

Answer 19

ok thanks
