To solve any equation, you do whatever you need to do
to wind up with the unknown quantity all alone on one side.
BUT ... whatever you do to one side of the equation, you must
also do to the other side.
Here, we have the
he original equation: -15 = a/5
Multiply each side by 5 : -75 = a
and bada-bing, THERE's the solution !
Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × 
× 
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × 
× 
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × 
+ 15C5 ×
P = ( 15C8 + 15C5 )
P = ( ( 
) + ( 
) )
P = ( 6435 + 3003 )
P = ( 9438)
P = 
( 4719)
P = 
P = 0.29
