Ivan

Answer:

Step-by-step explanation:

a) Yes.

$\forall\ a,b\ \in\ B,\ a+b\in B\ (since\ 0+0=0)$

b) Yes

$W=\{0,1,2,3,..,\}\ (whole\ numbers)\\\forall\ a,b\ \in\ 3W,\ a+b\in 3W\\since:\\a\ \in\ 3W \Longrightarrow\ \exists\ k_1\in W | a=3*k_1\\\\b\ \in\ 3W \Longrightarrow\ \exists\ k_2\in W | b=3*k_2\\\\a+b=3*k_1+3*k_2=3*(k_1+k_2) \in 3W\\$

c) Yes

$\forall n\ \in\ \mathbb{N}: \Longrightarrow\ n+1 \in\ \mathbb{N}\\$

d) No

$3\in V , 3+3=6\notin V\\$

You toss a coin and randomly select a number from 0 to 9 what is the probability of getting tails and selecting 3? 0.25 0.95 0 0

andre [41]

The correct answer is .05

To solve, find the decimal of each of the probabilities:

Flipping Tails: 1/2 ----> .5

Picking 3: 1/10-----> .10

Now, multiply them together:

.5 x .10 = .05

Hope this helps!
