If 7 coins are tossed, how many outcomes are there?

128 outcomes

Step-by-step explanation:

No. of outcomes for a coin is given by :

2^n [where n is the number of times a coin is tossed]

=> 2⁷

=> 2 x 2 x 2 x 2 x 2 x 2 x 2

=> 4 x 4 x 4 x 2

=> 16 x 8

=> 128

7 coins are tossed, each coin has two possibilities therefore total number of possibilities are 2^7 = 128. The possibilities of obtaining 4 heads and 3 tails is 7C4 = 7C3 = 35.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
