10. This question is based on the facts of Dakota Mining that we covered in class on September 20. We concluded that if Dakota has the option to wait to decide whether to invest in the lithium mining project until 2023, it should do so if the probability p of the Inflation Reduction Act being enacted is 60%. What is the smallest probability p for which Dakota should invest in the project at the start of 2022? Less than 65% Between 65\% and 70\% Between 70% and 75% Between 75% and 80% Between 80% and 85% Between 85% and 90% Between 90% and 95% Over 95%
