Find the value of (+328.62) – (+98.6). A. 230.02 B. 427.22 C. –427.22 D. –230.02

Jet001 [13]

Answer:

Option A - $(+328.62)-(+98.6)=230.02$

Step-by-step explanation:

We have given the expression $(+328.62)-(+98.6)$

We have to find the value of the expression ?

Solution :

Step 1 - Write the expression

$=(+328.62)-(+98.6)$

Step 2 - Applying symbol rule i.e. multiplication of positive into negative is always negative, $(-)(+)=(-)$

$=328.62-98.6$

Step 3 - Solve

$=230.02$

Therefore, The value of the expression is $(+328.62)-(+98.6)=230.02$

So, Option A is correct.

Scrat [10]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: State the number of outcomes possible for three tossing of a coin

Since a coin has two possible outcomes and is tossed three times, the total outcomes will be:

$\begin{gathered} 2^3=8 \\ 8\text{ outcomes} \end{gathered}$

STEP 2: Find the number of sample spaces for the three tosses

STEP 3: Get the outcomes of the events for which the second toss is tails

Hence, the answers are given as:

Sample Space:

$\lbrace HHH,HHT,HTH,HTT,THH,THT,TTH,TTT\rbrace$

The event that the second toss is tails:

$\lbrace HTH,HTT,TTH,TTT\rbrace$
