Remark

The formula for a discriminate is b² - 4*a*c

a = 2

b = 1

c = - 3

So the discriminate =

D = (1)² - 4*2*(-3)

D = 1 - - 24

D = 25

The weather forecast says there’s 70% probability of rain tomorrow. What are the odds against rain

krok68 [10]

Answer:

30%

Step-by-step explanation:

Key skills needed: Probability

1) There is a 70% chance of rain.

2) We need to find the chances against rain.

3) To do this, we need to use the fact that

70% + x = 100% (Since all the probabilities add up to 1 or 100%)

4) If you subtract 70% from both sides, x = 30%

5) This means the probability against rain is 30%.

Hope you understood and have a nice day!! :D
