Answer:
0.294
Step-by-step explanation:
The number of possible outcomes for 2 consecutive days is 2 (Friday, Saturday and Saturday,Sunday).
Prob( Friday, Saturday has rain) = 0.70*0.70* 0.30) = 0.147 (No rain Sunday)
Prob( Saturday/Sunday has rain) = 0.30*0.70*0.7) = 0.147 (No rain Friday)
Required Probability = 2*0.147
= 0.294.

Answer:
let's use Pythagoras theorem,
h²=b²+l²
so,
ad²=ac²+dc²
6²=ac²+3²
36-9=ac²=27
√27 can be written as 3√3,
hence ac= 3√3
