Im so confused at part b) is not 0.98 and i dont know what is it

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.

easy math just plug in a and b

step-by-step explanation:

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
