I need help with a 6th grade math problem

The forecast for tomorrow says that there is a 37% chance of rain. Describe the complimentary event and predict it's probability. Please help me figure this out and tell me how you get the anawer. Thank you.

37% = .37
1-.37= .63
.63 = 63%
So 63% of no rain.

if there is a 37% (.37) chance of rain.

then there is a 1 - .37 chance of no rain

.63 = 63% chance of not raining

63% chance no rain
