Based on meteorological records, the probability that it will show in a certain town on January 1st is 0.315. What is the probability that in a given year it will not show on January 1st in that town?
0.315
1.315
0.460
3 175
0.685

0.685

Step-by-step explanation:

For January 1 in that town, each year, there are only two possible outcomes. Either it snows, or it does not snows.

This means that snowing and not snowing are complementary events, that is, the sum of the probabilities of these events is 100% = decimal 1.

Then

0.315 probability it snows

1 - 0.315 = 0.685 probability that it will not snow. So the correct answer is 0.685.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
