a=-79/2=-391/2=-39.5
Step-by-step explanation:
a+45=11/2 subtract 45 from both sides
a=11/2-45 convert 45 to fraction 90/2
a=11-90/2 subtract 90 from 11 to get -79

We will only get a tornado if there is already a thunderstorm materializing
0.80 * 0.14 = 0.112
Probability of a tornado = 11.2%
There is a 100 - 14 = 86% chance of a tornado not being produced.
0.80 * 0.86 = 0.688
Probability of a storm and no tornado = 68.8%
