To calculate the probability that a baseball pitch is thrown with fewer than two strikes, we'll use the data provided:

• Total pitches thrown: $3495$
• Pitches with no strikes: $1231$
• Pitches with one strike: $908$
• Pitches with two strikes: $1356$

Step-by-Step Calculation:

1. Calculate the total number of pitches with fewer than two strikes:

   • This includes both pitches with no strikes and pitches with one strike. $\text{Pitches with fewer than two strikes} = 1231 + 908 = 2139$

2. Calculate the probability: $P(\text{Fewer than two strikes}) = \frac{\text{Pitches with fewer than two strikes}}{\text{Total pitches thrown}}$ $P(\text{Fewer than two strikes}) = \frac{2139}{3495}$

3. Simplify and round the probability to four decimal places: $P(\text{Fewer than two strikes}) = \frac{2139}{3495} \approx 0.6120$

Final Answer:

$P(\text{A baseball pitch thrown with fewer than two strikes}) = 0.6120$
