Step-by-step explanation:
Because both have magnetic fields
The value of the expression 2n - 1 when n = 7 is 13.
<h3>Equation</h3>
2n - 1
when n = 7
- Substitute n = 7 into the equation
2n - 1
= 2(7) - 1
= 14 - 1
= 13
<h3>What is mathematical expression?</h3><h3 />
Mathematical expression is an expression which involves the combination of numbers and variables in a valid way, in a function of addition, subtraction, multiplication, division and exponentiation
Therefore, the value of the expression 2n - 1 when n = 7 is 13.

The probability of landing on the 4 spinners divided into four equal parts will be P=25%
<h3>What is probability? </h3>
Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Here the spinner is divided into four parts of the colours green, red, yellow, and blue.So the number of the sample variable are:-
P(S)=[red,green,yellow,blue]=[4]
The favourable outcome is given as:-
F[s]=[1]
So the probability will be given by:-
P={1}÷{4}=0.25=0.25x 100=25\%
Hence the probability of landing on the 4 spinners divided into four equal parts will be P=25%
