Toss a paper cup into the air 100 times. After each toss record whether the cup lands on its bottom Class 9

Question 1.

Toss a paper cup into the air 100 times. After each toss record whether the cup lands on its bottom, upside down on its top or on its side (See Figure). Assign probabilities to the outcomes by using experimental probability. Class 9

Figure Paper cup landing positions (left to right) - bottom, top and side.

Solution:

The answer depends on the actual experiment.

Suppose, Bottom = 35 times

Upside down on its Top = 25 times

Side = 40 times

Total number of tosses = 100

Experimental probability of cup landing on bottom:

P(Bottom) = $\begin{aligned} & =\frac{\text { Number of times cup lands on bottom }}{\text { Total number of tosses }} \\ & =\frac{35}{100}=0.35\end{aligned}$

Experimental probability of cup landing on top:

P(Top) $\begin{aligned} & =\frac{\text { Number of times cup lands on top }}{\text { Total number of tosses }} \\ & =\frac{25}{100}=0.25\end{aligned}$

Experimental probability of cup landing on side:

P(Side) = $\begin{aligned} & =\frac{\text { Number of times cup lands on sides }}{\text { Total number of tosses }} \\ & =\frac{40}{100}=0.40\end{aligned}$

[Note: The above question has multiple solutions. Students may write other solution depending on the experiment]
