Suppose the chance of winning a game is 1/50. If you play the game 50 times independently, is it certain that you will win? If n
arlik [135]

We are given chance of winning a game is 1/50.

In decimal form 1/50 could be written as 0.02.

So, for each game, the chance of winning is 0.02.

Therefore, chance of loss would be = 1 -(0.02) = 0.98.

Chance of loss of 50 independent games = 0.98*0.98*0.98*0.98...... upto 50 times, that is (0.98)^50.

The chance of winning at least once = 1 - (0.98)^50.

We got (0.98)^50 = 0.36417

Therefore, 1 - (0.98)^50 = 1 - 0.36417.

We get 0.63583.

Therefore, correct option is c. 0.6358.

Which describes the relationship between &lt;1 and &lt;2 &lt;1 and &lt;2 Are complementary angles &lt;1 and &lt;2 Are equivalent
AleksandrR [38]

Answer:

See Explanation Below (Incomplete Question)

Step-by-step explanation:

Question is incomplete.

I'll answer this question on a general term.

(See attachment below)

Figure 1 is used to illustrate complementary angles. Two angles are said to be complementary when they add up to 90°.

So, in figure 1, <1 and <2 are complementary because <1 + <2 = 90°

Figure 2 illustrates supplementary angles. Two angles are said to be supplementary when they add up to 180°.

So, in figure 2, <1 and <2 are supplementary because <1 + <2 = 180°

Figure 3 illustrates adjacent angles. Two angles are said to be adjacent when they share the and vertex

Figure 4 illustrates equivalent angles. Two angles are said to be supplementary when they are equal.

So, in figure 4, <1 and <2 are equivalent because <1 = <2
