"Tossing a die" is assumed to mean choosing a random face of a cube with faces numbered 1 through 6 such that the probability of choosing any particular face (number) is 1/6.

Event a is "observe a 2". Event b is "observe an even number". The event "a and b" is "observe 2 and an even number". This matches precisely the description for event a. In other words

... a and b = a

... p(a and b) = p(a) = p(choosing 2) = 1/6

Answer:

Option- B

An experiment involves tossing a die. these are some of the events during which we can be able to observe an even number.

Step-by-step explanation:

It is more obviously to know that there will be six sides for us to observe and each time we will get an even number to observe during the process.So, it all goes with the mechanisms of the probability that are taken under considerations when we speak about such events to happen.

How does moving the place of a digit change its value

AlexFokin [52]

In the familiar decimal number system that we use every day, moving the place
of a digit changes its value by a power of 10 .

In a system of numbers to any other base, moving the place of a digit changes
its value by a power of whatever the base of that number system is.

Roberto rowed 20 miles downstream in 2.5 hours. The trip back, however, took him 5 hours. Find the rate that Roberto rows in sti

almond37 [142]

Answer:

Roberto's speed in still water is 6 miles/hour and the river speed is 2 miles/hour

Step-by-step explanation:

Relative Speed

When a body is moving at a constant speed v, the distance traveled in a time t is:

$d=v.t$

When Roberto rows downstream, his speed in still water is added to the speed of the water, making it easier to travel the required distance.

When Roberto rows upstream, his speed in still water is affected by the speed of the water, both are subtracted and the required distance is covered in more time.

Let's call

x = Roberto's rowing speed in still water

y = Speed of the river current

The speed when rowing downstream is x+y, thus the distance traveled is

$d=(x+y).t_1$
