Roll two fair dice. Each die has six faces. A. Let A be the event that either a 3 or 4 is rolled first followed by an odd number

zhenek [66]

Answer:

A. 0.16

B. 0.58

C. No

D. Dependent

Step-by-step explanation:

The sampling space has 36 outcomes.

The event A has 6 outcomes (3,1), (3,3), (3,5), (4,1), (4,3),(4,5)

So P(A)= 6/36 = 0.16

The table in the picture shows the 15 outcomes that are not allowed, so there are 36-15 = 21 possible outcomes for B and its probability is 21/36 = 0.58

Are A and B mutually exclusive events?

No since their intersection is not empty, for example (3,1) belongs to both A and B

In order for A and B to be independent, it must happen that

P(A∩B)=P(A)P(B)

A∩B={(3,1),(3,3),(4,1)} so P(A∩B) = 3/36

whereas

P(A)P(B) = (6/36)(21/36) = (1/6)(7/12)=7/72

So A and B are not independent.

There are some frogs and some lily pads at a pond. If lily pads with frogs on them have two frogs each, then there are 3 lily pa

Bogdan [553]

Frogs are at the pond = 12.

Given,

There are some frogs and some lily pads at a pond. If lily pads with frogs on them have two frogs each, then there are 3 lily pads with no frogs on them. If each lily pad has exactly one frog on it, then there are 3 frogs with no lily pad.

= 2( n-3) = n+3

= 2n -6 = n+3

=> n = 9

9 pads, 12 frogs.

Hence, Frogs are at the pond = 12.

How to divide like that

Lady bird [3.3K]

Step-by-step explanation:

First you divide the numerator and the denominator by 10, it leaves you with 1500/21 , now you again divide the numerator and denominator by 3 and you get 500/7.

Remember, you ought to divide the numerator and the denominator only by the numbers which are their common factors or in a more easier way, you only divide them by a number which divides them both simultaneously.
