The experimental probability of a coin landing on heads is 7/12. If the coin landed on tails 30 times, find the number of tosses

1 answer:

4 0

Answer: 72 tosses

Explanation: If the probability of landing heads is 7/12, the probability of landing tails is 5/12. So then you do cross multiplication, where you multiply the 12 and the 30, equalling 360. Then divide that by 5, equalling 72.

2.3*10-5=18

3.1*10 (dunno what to do with 12, there's no sign) but = 31 (that's w/o the 12)

Now multiply which = 558 (do whatever with the 12 to the equation.
