Answer:
0.3 or 30%
Step-by-step explanation:
Since no innocent student will ever be caught, the probability that a student sends an email and/or text message during a lecture AND gets caught is given by the product of the probability of a student sending a message (60%) by the probability of the professor catching them (50%) :

The probability is 0.3 or 30%.
<h2>
Answer:</h2>
is 3 ohms
<h2>
Step-by-step explanation:</h2>
In a circuit containing two resistors
and
connected together in parallel, the total resistance
is given by;
---------(i)
<em>Make </em>
<em> subject of the formula;</em>
=>
=> 
=>
---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=> 

= 3Ω
Therefore, the value of
= 3 ohms or
= 3Ω
